Hi all, selling some stuff:
All prices are +P&P except the amp modules(UK only).
4 x Fully constructed and tested GB150 amplifier modules. TWO REMAINING
These are also known as the SKA (Simple Killer Amp) and were designed and built by the talented Greg Ball.
These are absolutely superb little amplifier modules. Stupidly daft value for money. I've directly compared these to AKSA 55N+, Roksan Kandy Mk3 and a Bryston 9BSST, the SKA was preferred and the Bryston retails for over £3k !
Includes construction details.
I posted a few paragraphs of thoughts on the GB150 sound:
| quote: | Anyway I decided to start out with some of the really good quality recordings I have and the first was the Andreas Vollenweider' "Vox" album. There's some great acoustic peices here that mix synthesized with natural. The SKA really is a top notch amp to the extent that its actually hard to fault, at least for me anyway, perhaps I haven't heard enough excellent amps? Eitherway I seriously doubt anybody would rate this amp as less than very good and consider the price that Greg is asking... he could ask double and I'd still have payed it.
Another important thing to mention is that the SKA's I have use only base components, so no fancy blackgates or other expensive electrolytics, no silver mica's, no 0.01% resistors etc. so in other words there's actually room for improvement however small it could be. But its interesting to see that design does so well in standard guise, I guess Greg' anal approach to design looks more toward layout and topology than diminishing returns offered from the esoteric components route. But if anyone want to hotrod one of these its entirely possible.
The biggest thing for me about this amp is its sharp but extremely smooth character. A contradiction? Not at all, its got top draw detail but it always seems to presented with a nice natural edge. Greg cites this design as low distortion (~0.008%) but to my ears it isn't like some of the other low distortion designs, its not bright and over hyped but its feels just as detailed with a really appealing softer edge that makes listening very easy. More refined overall I'd say is the best way of putting it and especially in the upper frequencies.
Soundstaging is amongst the best I've heard from a solidstate designs and really only seems to be limited by the recording and the rest of your equipment. I'm feeding it with some great quality DAC's and bit perfect playback so this gives the SKA one of the best signals it can hope for. The SKA doesn't flatter rubbish recordings and they still sound rough but not to the extent that you couldn't enjoy them its just that in comparison to the better/best recording you don't get the awesome realism and that really involving nature.
What it does do with the right recording is completely fool you into thinking that your actually listening to the real thing. It does a great job of creating spaces and sizes, it seems to be able to relate the whole picture with proper proportions without blowing things up or bringing details to the fore that perhaps should be so obvious. Like I said the best word for this is natural, its often used word and there's varying degree's of it but here it really does feel right.
Tonality was perhaps covered in the last bit but just to be sure; its just plain natural Go play the piano (if you have one) or another musical instrument and then go listen to something similar on the SKA. It sounds very nearly as real. Few amps I've heard do this. If only it had an ounce more detail it would be heaven but then again my speakers are most likely the weak link though that's about to sorted out in a big way.
Imaging is drool worthy. I'm sure some folks can relate to what I'm about to write; have you ever heard those systems that have the kind of imaging that suspend disbelief? Well the SKA is nearly as good and again my speakers and room are probably the weak link so I expect improvments in the future. When playback is going on you hear very precise locations of certain sound or voices. You even get a good sense of depth with it being apparent that things are further away than other sounds. Another big deal is the amps great way with folly effect. I listened to many tracks and a few had me thinking that I could hear reflections off walls behind me but what I was actually hearing was the acoustic space of the recording, its a amazing effect to hear and always puts a smile on my face.
Bass again is better than I'm used to with the AKSA. Tight, smooth and rhythmic. I think that bass performance of many amps is one the biggest let downs and that a well conrtolled bass lift the entire performance on a notch. Room problems could be blamed but I do use DRC so that isn't a big problem for me.
Overall I'd have to say that this is the best DIY design I've come across yet and just happens to be the cheapest too. Its very hard to fault and I really do think that any real improvements above and beyond what performance is offered by the SKA isn't to be had from better amp design but from considerations of room and better loudspeakers. |

Superb value at £40 each
-------------------------------------------------------------------------------------------------
2 x Fully constructed and tested GB300 amplifier modules
Same as above but twice the power at 300w into 8ohm. Same superb sound but with better handling of tough loads, high SPL and more dynamic. IMO the GB300 is very slightly better than the already excellent GB150.
Includes construction details.

Superb value at £60 each
-------------------------------------------------------------------------------------------------
45-0-45 800VA Toroid
Would suit the GB300's above perfectly.
Dual 45v secondaries and dual 120/110v primaries, perfectly OK for UK mains since I've been using it that way, just wire the primaries in parallel. Includes a couple of neoprene vibration cushions and all mounting accessories. Absolutely no hum from this. Bought from farnell for £48 a couple of months ago. As new condition with perfect leads (not chopped or mangled) and never mounted in a case.
£25 please
Forgot the photo for this one but I think everyone knows what one of these are by now :)
-------------------------------------------------------------------------------------------------
Tons of random bits SOLD
I really can't be bothered to catalog all this so I'll just list roughly what included, think of it as lucky dip :D
- A thousand or so resistors, varies values and virtually all 0.5/0.25w 1% types and around 12 large 7w types + 10w ceramics.
- A few Blackgates 50v standard type capacitors
- Semiconductors (LN5819, BC559, BC549C, N5819, MPSA42 etc. etc.)
- Around 10x BB OPA2134 Opamps
- Fuses + PCB fuse mounts
- PCB pins
- 4 x 35A 600v high quality metal cased bridge rectifiers

- A fair few caps from the likes of Vishay, Elna, Nichicon. Mostly polystyrene types and electrolytic
- XLR connector, 4 x gold plated and chunky binding posts, 1/4" TRS connector.
- TO220 Mica washers and mounting hardware
- Other stuff
Please, please don't ask me to identify the items, I've priced them to take into the account of the uncertainty of the contents.
BTW: The components are virtually all clearly marked, so you can identify them quickly.
£30 to help me clear this stuff out please

Microphone Preamp PCB + 2 panasonic WMA61a mic capsules SOLD
Vikash very kindly gave these to me and rather than never use them I thought I'd return the favour to someone else. Details can be found on Vikash's website.
Free!

Selling the SKAs? What on earth is your new plan? :)
I'll take one of the preamp PCBs with the capsule, and I'll check the bank account tomorrow to see if I have enough cash for the components. |

Hi Al,
I've just bought a B-Grade Chord 1200E standard from Movement Audio. (some minor scratches to the top and two very small identations.)
http://www.chordelectronics.co.uk/p...etail.asp?id=14
I'm on the look out for another 2 either the 1200c or 1200e. But they aren't cheap. Fantastic build and the sound is just so 'spot' on. Heard one of these at the Northern Hifi Show at the Manchester Radisson Hotel this year and was absolutely gobsmacked, as soon as saw the the b-grade model for silly money I just ordered it without even thinking.
Hasn't arrived yet but I know what to expect so the GB are going, still very strong amps though just not Chord territory.
The preamp and electrets are yours, let me know about the others. |

| GB300's sold to gaborbela (pending payment). |
|
|
| ShinOBIWAN |
I've also got 2x 4U rack mount cases that someone can have FOC if they collect. They're in as new shape but I sprayed the front panel gloss black and its started to flake off - obviously I didn't do a very good job :) The Fronts want rubbing down and redoing with some metal primer this time, would be perfect if this was done.
I'll post some pics tommorow evening but these would be good for a DIY amp project. Cost me Around £40 each from Maplins if I remember. |

How about, forget it. :)
I'd rather let them gather dust, just in case I did need them in future. Sorry but £20 is an insult for amps of this calibre, go back read my comments and then offer the asking price if your truely interested.
Sheesh, the cheek of some folks. And from AH of all people who should know the value of a good amp.
Offers considered but not 50% off an already stupidly cheap price for the performance on offer. Like I said before, these compared very favourably with a £3k Bryston and the AKSA 55N+. Enough said really. |

When you offer secondhand amp modules for sale
of cause I am going to try to get them cheaper.
regardless of their quality
40 pounds works out to be about $100.00 AUS
I can buy the kit for that
:D
So please no offence, its just business... |

No problems.
As you've probably gathered, I think pretty highly of the modules, more so than any DIY design and commercial design I've had before so I'd rather keep them for a rainy day than sell them for peanuts. Afterall £20 only buys you a couple of CD's here in the UK let alone an amp that sounds like it should have a £2k price tag.
The price is really aimed at folks in the UK since £40 includes P&P and the modules are built, tested and guaranteed working. If your comparing like for like you really should be quoting Gregs pre-built option which works out at around $155AUS per module. But since you build amps for a living its not such a big deal to build the kit up for others it maybe. I guess the postage to Australia is less than economical too.
Like I said before, I'm open to sensible offers. |
|
|
| ShinOBIWAN |
I almost forgot:
I have an assortment of Blackgate standard and N types that will fit the GB150 and GB300 in all the critical positions that Greg has cited to offer the most improvement. There's also Audionote Tantalum resistors to compliment the Blackgates.
These are offered to anyone buying the modules or simply to anyone interested in upgrading their own GB amps.
Let me know if you need more details and a price. |

Hi, I am interested in the: Microphone Preamp PCB + 2 panasonic WMA61a mic capsules
Yes, my dutch eyes saw the word "free" ;). I can trade for parts if you need those. |
|
|
| pinkmouse |
Too late J-P, I got there first! ;)
Ant, I will take those components as well, email me from your Paypal addy and I'll send the money through. |
|
|

| OK Al, email sent. |
|
|
| ShinOBIWAN |
Al could you do me a favour and edit my original post to show that these are sold:
2 x GB150
MicPre PCB
Box of random components |
|
|
| ShinOBIWAN |
Also for sale:
2x 35v 300VA toroids
The toroids are dual 35v secondaries with 300VA rating and single 240v primary winding. These are top notch audio grade toroids: Its an encapsulated design featured a shielding layer then an ABS outershell and finally a resin pour to hold the whole thing together. The hum is absolutely zero and the EMI is reduced even further over a conventional toroid. Unfortunately this means they are somewhat larger and heavier than you would otherwise expect.
Perfect for the GB150's and I believe these would also be suitable for the AKSA 100 series.
£20 each since they're as new with the leadouts in perfect condition.
45v 800VA Toroid
Would suit the GB300's above perfectly.
Dual 45v secondaries and dual 120/110v primaries, perfectly OK for UK mains since I've been using it that way, just wire the primaries in parallel. Includes a couple of neoprene vibration cushions and all mounting accessories. Absolutely no hum from this. Bought from farnell for £48 a couple of months ago.

Hotmail is acting up, tried to send you an email but it just keeps giving me the two finger salute - typical Microsoft.
What I wanted to say in the email was that the postage to Australia for these things is ridiculous - more than the toroids themselves! Its a hefty parcel after you've add in the weight of the packaging and protection to ensure they arrive safetly.
I think its only really a sensible option for folks in the UK or maybe Europe. |

What Rich said :)
I'm looking to get rid of them but this is about as cheap as I'll go. If it comes to it, I'll have to box them up and put them in the loft or something.
If I had more time I'd definitely be keeping them but sadly they'll likely remain unfinished.
I've also got 2 variable regulated PSU's with tiny encapsulated toroids that I'll never use now, here's a link for those interested:

For all those that have bought something in this thread:
I still haven't posted them unfortunately. I've had some trouble getting hold of packaging and boxes to ensure they arrive safetly. I really should have sorted this out before putting them up for sale. It doesn't help that I work from 8.30am until 5pm weekdays and Saturday this means that getting to the post office is anything but easy. Don't worry though its in hand. I've sold plenty of stuff here on DIYAudio and never let anyone down. The plan is to sneak off into town at dinner and post these but it won't be happening until Friday unfortunately.
I'll email you all with the tracking information on that day.
Appologies,

To all those waiting for the bits they have bought:

Thankyou for your patience and hope you enjoy whatever you've bought.
Thanks,
Ant
PS. John I haven't sent out the cases or linkwitz boards just in case you want the PSU's as well - saves you extra postage costs. Could you please let me know eitherway and I'll sort out accordingly. |

I'll also vouch for Mr Shinobiwan's integrity, I bought a good number of drivers off him before christmas, the package took about 8 weeks to arrive, but the post marks all agreed with when he said he has posted it on time, I think his local post office is just ultra slack!
I wouldn't hesitate in doing business with him again. |

Guys, thanks for vouching for me.
My email is a mess at the moment so instead of trying to track down individuals I'll just post the tracking info here:
All these were sent 1st Class Registered:- Daniel(GB150) - DK 9739 5115 1GB
- Steve(GB300) - DK 9739 5116 5GB
- James(Wallin) - DK 9739 5117 9GB
These were sent via Standard Parcels service because of the weight, this means that these parcels aren't trackable but are insured:- Andrew(GB150+, 3x Toroids)
- John(PSU's, LT's, Cases)
Sorry for delay but I will do whatever I can to help, including prompt refunds should it come to that. |

Not questioning anyone's integrity. ShinObiwan is a significant member of the DIY community here, and I've read many of his contributions at diyAudio with interest.
You know how it is waiting for anything in the post - particularly when it's something fun - you just want to know when it's going to turn up.
Looking forward to getting the amps soon.
Dan
p.s. I've already built a stereo GB150 based amp, and it's everthing people here have been saying. The second pair is for bi-amping. |

I'm sure you'll love those GB150's when they eventually arrive. Awesome sound for the money and probably in my top 5 amps, definitely a nice amp.
The only problems that I've had with them is that they sound a tad edgy and blurred on really revealing speakers, they were missing some of the crispness that I like. I had them hooked upto ATC SCM7's and they sounded great but when I tried them out on my DIY designs they lacked just a tad. |
|
|
| Spartacus |
| I suspect there is more to be gained from the SKA design. I've posted in the SKA constructor's thread with a thought. |

Hi again Dan,
On the GB's I've messed around with a few 'highend' components such as Blackgates and Audionote tantalum resistors. I also had Gregs PSRR mod on them and strong, low ripple and large resevoir power supplies.
I'm not saying I'd maxed them out or anything like that but they weren't standard. These mods all have a subtle impact on the sound through mainly refining it. They don't change the core sound signature though.
When you consider that they're only around £100 a channel to build (including PS and torroid) then you realise that they're extremely good value. A mate and I compared the GB300's to a Bryston 9BSST and thought them to a little sound better and that's a 5ch amp that retails for £3k. They're great amps as you well know but like everything else DIY, there's compromises in the sound. What these mean is to be evaluated by the end user.
I'm not dragging the GB's down, quite the opposite, but I'm just bringing in a reality check and explaining one of the reasons why I sold them.
I recently heard a highend gainclone implementation in a friends system and was blown away by the quality, so this is the next stop for me. I'm looking forward to Gregs opamp frontended version of the SKA and I'd also like to checkout one of the well regarded Aleph designs in the near future too. So far I've built or done extensive listening to 5 different designs; ESP P101, AKSA 55N+, Hypex UcD700AD, GB150 and GB300. All have been either good or very good. The real reward is just hearing the differences between each and trying to find something that fits and compliments your system. |

ShinoBIWAN,
I thought you had settled on the LNA amps? - did the GC's sound better? What was the detail on these - hardwired/pcb, regulated psu/SMPS, etc. Would like to hear details

Hi John,
The LNA's? Are you talking about Dan Banquer's design?
Those GC's I heard were part of a friends system, my own are still in bits. I do know that they are Audiosector parts which follow most of Peter's recommendations for his Patek SE design. My mate is using 160VA 18v traffo's in dual mono config and they were LM3875 based with Blackgate N types on coupling and Blackgate STD's on the supply. He was using the snubbers and zobel with his design I don't plan on either of those.
I've decided to copy this design myself since its already left a good impression. It seems that using an SMPS (Nuuk supplies them) with the GC's may bring further improvements along with buffered input. Since this is such a simple design there's lots of possiblities for easy and cheap mods.
I'm not expecting miracles from the GC's and nor do I think they're 'better' than the GB's. The way I see it is they're cheap, fun and easy to mod. In the meantime I'll be waiting for Greg's OSKA design. |

Glad they've arrived. I think that everybody has confirmed their stuff has arrived now.
James - sorry about the binding post, I'll forward them onto you.
Andrew - I'd removed some blackgates and other expensive components from your boards prior to selling them. However I've just realised the I haven't replaced the 330uf coupling caps. Please don't go ahead and try the amps since they'll get fryed. I can forward these two that I have here if you don't have any. Not sure how useful they are though because the leads look a bit of mess. |

Hi Shin,
thanks for confirming 330, the schematic does not give a value, it's just off the edge of the zerox.
I have 330uF 63V with correct diam and pin pitch, are these an equivalent?
Have you got the correspondence from Greg re modifications? Email if it's convenient. |
|
|
| ShinOBIWAN |
Yep its 330uf 63v at C6 & C7.
I don't appear to have your email anymore. Could you mail me your address and I'll send the manual and mods in an attachment. |

Cheers, appreciate it - especially as I managed to snap one of the others (teach me to overtighten...)
