Hey Ashok, George,
I am looking for a relaible 25W ckt.
BTW what is the biggest DIY SE amp? I was hoping to get 25W SE. Crazy?

I'm not able to shed too much light on SE amps-my experience is more speaker and subwoofer related. My two recent amp projects were the AKSA ss amp ( 2003) and a Welborne Labs pp amp(2001) before that. I did another one from Marchand (MOSFET) before that. Will be more than happy to shed light on any of these projects!
I have done a lot of desk research, on kits, but, as you know-there is no substitute for hands on! One SE (Parallel SE, not SET) amp that I have looked at as a future project, produces 30wpc in Class A- is the Edison 60 kit from Audion UK.
The problem here is that we depend a lot of internet reviews, since we dont have much choice of products or kits here in India, and dont have the opportunity to audition these things using our own speakers and our music! In addition valve amplication is looked at as obsolete, by many people here!

Hi Navin.
25 wpc SE Class A ! Humm. Then a 845 triode is the way to go. The army used the 845 in their transmitters. A few years ago they auctioned their tubes off as war surplus. You may be able to buy a set of 845 triode at Teletone in LM Road Mumbai.
Transformer could be an issue. You have two options. Import one from your trips to US. A Hammond 1642SE at approx $200 each. Cheaper options could be available from other manufacturers. You will need to look around.
Alternative is to wind your own. My now demised laptop had a fantastic bookmark on how to do this. That guy had given complete details on all the parameter that you will need to wind your own 845 output transformer. I should search again for the same.
Cadence of Pune had a 845 model in their range. It was driving their ESL quite beautifully. I auditioned that combi in year 2000. Just that it was too expensive I thought. Speak to Mahendra Dave. He is one of the threesome that make up Cadence. His shop/demo room is called Oceania in Pune.
An 845 will look intimidating to a nub (it should). But I guess a guy of your expetise is ideally suited to tackle that. If you need less power then look for 300B projects. I know a person in Jsr who bought a 300B kit from UK. But I’ve never seriously auditioned his build till now. Perhaps this Saturday I may be able to induce him to invite me over for a round of drinks. Judging by net reviews 300B triode amps appear to be a good thing going.
Those were triodes. If you are looking for a pentode class A then options are several. They are cheaper and a bit louder too. An EL34 SE will give you around 9 good wpc. A 6L6 will give around 11 wpc (6 if triode connected) and so on.
At the moment my full time amp is a 6BQ5 Class A SE. 5 wpc of absolute bliss. I originally built it for my PC. During late night listening sessions it gives out serious goose bumps. Another unfinished amp project currently with me involves a 6V6 Beam Tetrode. Should be completing it before the year ends.
Do have a look at the following links for 845 (an other) Class A projects. The first link has some details on winding a 845 output transformer too. Though not as good as the line I mentioned earlier. Second link is Bonavolta’ s extensive tube resource. My amps are based on circuits from that site.
http://www.recherche.enac.fr/~puechmor/e_triode.html
http://www.bonavolta.ch/hobby/en/audio/845.htm (good all around source for nub)
Realistically speaking you should allot 12 months for a valve amp project. Collecting all the components will take at least half of that time. I would urge that you dig up as much resources as possible. You will be well rewarded in the end.
George,
isnt that a fantastic thing 😀 At least that keeps that cost of tubes down.
Also, your mail server is playing truant. My response to your last email bounced back.

There have been some problems with our mail server let me talk to the folks in the US and see how it can be fixed. You're second person who's told me about this. Can you forward your reply to my last email to the following backup id: gjo1314@yahoo.co.in?
Many thanks.
As our resident China hand, I am sending you something with a Chinese flavour offlist!
Navin:
I am not a hardcore DIYer on the amp front, preferring to buy kits because the headache of procuring parts here is too much for me. Imported kits generally are the easiest way for me, something that may not have come through in my last post..

thanks for teh 845 tip. I was considering a 300B at first. However I am not sure if a 300B will deliver teh power. My BIL (sisters hubby is also doing a 300B and he lives in sing so I expect to get some pointers from him). my speakers will be push push 8546 XOed to 9900 in a large room (350sq. ft. 10 ft ceiling) so I woud like to have a bit of power.
will check both links when i get the time. however i would like to wind my own tranny as i dont think i owuld ever be able to carry a tranny from the US esp post 9/11.
thanks again. seee u guys tuesday.

Re: Made in China
Does this mean that in the final analysis, we DIYers in India will never get good components for high quality audio because the Indian customer will always look for combo systems with aerodrome displays for Rs.10,000? I once contacted the Nova Audio chap; he was listed as the Indian distro for Scanspeak. He said he was not involved with Scanspeak/Vifa any more; there were no volumes. He'd even informed Scanspeak to remove his name from their Website. Is this the story of everything in high quality audio components in India? Will we have good drivers in India only when an entrepreneur sets up a driver design, manufacturing, and export facility here? If that's the case, then we already have Peerless India, and it still doesn't seem to be doing you and me any good. They just don't care about supplying the local market reliably. It's very confusing. 🙂
Tarun
You're so right about this export thing. Cadence primarily exports, and one can see their quality. Sonodyne apparently exports; I have no details, but I believe their equipment now is better than the stuff my dad bought in 1983.gjo said:Many of their products are export driven, which is not true in India, and this may be a key factor in defining quality for home Vs foreign markets,

Wow! Interesting stuff. Can you comment on the difference in the sound of the solid state amps you've built? Does the Aksa really sound good enough to justify the price of their kits? I believe their kits come with high-priced passive components. Did you hear any audible difference using those components instead of good quality non-audiophile components? (For instance, difference between a Black Gate instead of a non-audiophile good quality metallised polyester for coupling cap, or Caddock resistors instead of the vanilla wirewound power resistors in the OPS.)gjo said:My two recent amp projects were the AKSA ss amp ( 2003) and a Welborne Labs pp amp(2001) before that.

And since you've done so much checking out of kits and designs, what do you think of the Randy Slone designs/kits? I've been thinking of building one of his designs.
And don't the courier charges of getting a kit like the Aksa from Australia to here just throw the prices off-gear? How expensive is the shipping?
Thanks and regards,

Eminence Specs
How about going to the Eminence site:
http://www.eminence.com
or more specifically:
http://editweb.iglou.com/eminence/eminence/pages/products02/neo/neo2515.htm#neo2515top
Now, whether you can believe their graphs.........
One reason that people like to use pro drivers in ported enclosures is because the x-max is a lot less at lower
frequencies. The reason that people use pro drivers is their low distortion so it's best to not increase the distortion too much by a lot of x-max. Be that as it may, I believe that the Rushmore speaker by Pass has a sealed cabinet and they have a tendancy to use filter shaping on their bass drivers, so clearly it can work with the right pro driver.

Re: Re: Made in China
It's about the money. How many people you know are willing to spend Rs. 100,000 on a stereo system (CD+amp+speakers). Khushroo for example was happy that he sold 2 pairs of his Manger 2 way for Rs. 180,000. On the other hand US$2000 is quite easily spent by someone in the US.
For the Indian market Vifa/SS/D-S-T operate out of thiland. they have a much bigger audio market than India. 2 reasons. Video never really completely killed the audio star there. they dont produce 800 movies a year. The Thai have a affinity for good music - dont ask me why but you can ask Micheal Barnes (www.norh.com). He managed to make a business there (post HP).
Singapore with 3 million has a bigger market than India. Indian dont have thet kind of disposable income that will take another generation or more. Indians have still have to afford one house per family, 3 meals a day, a proper educational/vocational system that caters to a bulk of the population.
Despite the lack of audiophiles, DIYers are even rarer to find in India. Most of my friends and colleagues are not handy with a screw driver leave alone a soldering gun and they have BE degrees. In India it is easier and cheap to call the neighbourhod electrician, plumber, carpenter than do the job yourself.

Hi Tarun
I got the AKSA kit shipped to the US and brought it back with me last March. It was with the Nirvana upgrade. It sounds really good. I picked up a couple fo toroidals and a box, so it is a dual mono. I didnt pay any customs duty at Bombay though the guy there looked at the large heatsink and tried to give me a hard time.
The Welborne Labs pp amp cost much more than the AKSA, uses a lot of high quality components(I havent yet upgraded with Caddocks and Mulitcaps) so I dont know how it will sound after the upgrade.It came as a complete kit, I didnt use anything procured locally.
By and large I have tried to get feedback from other users before buying anything-this is relatively easy in the US, so I would suggest you do this before spending US$ on any new purchse from there..
I dont have too many points of refernce for the two amps, but at this point prefer the pp to the AKSA.

Let me clarify a little more-my approach is to go for good kits because I dont have the time and inclination to locate parts here. I did it once for a subwoofer amp and decided right then and there that for me it was not worth the time.
Building the AKSA amp is easy, the instructions are clear, and Hugh Dean is an great resource-he usually answers email very fast and is patient. I found his support to be quite outstanding. In addition there is a good user forum on his site which has a lot of traffic, as well as a good FAQ. I bought the unit with the Nirvana upgrade and didnt listen to the stock unit, so dont know about how the upgrade improved the sound!
Assembling valve amps are far more complex and unless the instructions are clear can cause you problems. I found assembling the Welborne Labs kit to be quite difficult -the complexity is of a higher level, and the diagnostics were nowhere as comprehensive as the AKSA. This is not a negative comment-most valve amps are more complex, period! I did not realise this early in the day and had someone to assist me, who was not upto the task. I had a lot of initial teething problems with it, until I found a valve ustaad-who fixed my problems, though it took some time! Let me tell you that local valve ustaads are slowly getting extinct..
Now for the sound. Valves amps do sound different compared to solid state, and there are a lot of web reviews etc written by people who can describe things better than me. My Welborne amp has better bass, and better definition than the AKSA, but both are good. I listen to both amps, but nowadays mostly to the Welborne, whereas until about two months ago it was mostly to the AKSA. My speakers are 94db sensitivity so 35 or 55 watts is plenty of power! My other speaker system is 84 db and also sounds nice with either of these..I havent listened to any other valve amps so I cant compare one with mine.
If you want to know more, do let me know if you're in Bangalore, I'll arrange an audition in my house for you!
I have also picked up a couple of subwoofer plate amps from stryke.com, because these are switchable for 110/220V, have a built in crossover and are plug and play, so to speak! They work very well for me.

Re: Re: Re: Made in China
The only exceptions that I find to this rule are when brand-conscious yuppies buy audio systems as status symbols. In the audio system market, this unfortunately means Bose speakers. Probably 90% of the components-based systems I've seen in India have Bose Acoustimass systems, gracing the houses of high-income yuppies.
Tarun
Though I agree with you 99%, I also feel that it's not just about the money. People spend a lot on expensive motorcycles when cheaper ones are available, etc. (See the number of Eliminators and Enticers on the roads.) I think when it comes to music, most educated and somewhat affluent people simply don't sit down and listen to music. Hence, for them, a Rs.10K combo system is as useful as a Rs.100K system built with better quality separates.navin said:It's about the money.

Nice.
Hi Ashok,
Don't apologise. The amp looks very nice. Except for a few people it is hard to get something done looking nice on a one off basis.
This one really looks nice. Trust it sounds as good.
How do you like the sound of the EL84 SE ?
What kind of bandwidth does it have? Delta audio transformers ?
Can you compare it against any other amp?
Cheers,
Ashok.

Re: Nice.
Tarun: your brahminical analysis makes eminent sense 🙂. I'm Brahmin and DIY’er. Unfortunately, I ain’t good in either !
In a word MAGICAL. I listen to it around round the clock. Can’t detect even a bit of hum or noise even if I stick my ears into the speakers. Stargrounding and short leads all around. No fancy caps. Generic MKP's and Carbon resistors. Wirewound Pots. BEL EL84+ECC82 and Mullard EZ81.
I don’t have the equipment to measure bandwidth. But I think its limited only by the speakers that I have. Very open and relaxed sound. You can clearly make out each instrument and their placement. Dynamics are captured fully at least for the kind of music that I listen to.
A few weeks ago I had almost 30 people over for a bash. This amp played thro the evening aided only by a flimsy Polk Audio sub flinched from my wife's HT setup. It was never short on power delivery.
Output transformers are nos Phillips. I fabricated aluminium enclosures and potted them with industrial grade resin. Earlier I had used Hammond 1628SE. A few months ago, I started on a 6V6 project and the Hammond is now powering the one channel proto. But I find the EL84 slightly better sounding. Delta is a good, but they only have PP. I have used Delta in the past and quite happy with them.
Thanks for the complement !

Re: Re: Nice.
Jokes apart, please don't misunderstand my remarks about Brahminical attitude having anything to do with the Brahmin caste of the caste system. I'm a card-carrying Brahmin too 😀 (I wear the sacred thread), but that's not the kind of thing I was referring to.
The reason I use the term "Brahminical" to describe this attitude is because in our ancient traditions, the caste which was considered the "highest" was the one which dealt with purely abstract thoughts and ideas. The blacksmith was deemed "lower" than the mathematician and philosopher. The caste system may have weakened with the years ... in fact, it certainly has ... but this value system has somehow remained, I fear. Hence my use of the term. Even today, you occasionally find this attitude embedded in random samples of educated Indians from all castes and communities. I feel this is part of the reason why we gravitate so naturally to "pure thought" disciplines like software, but have had to struggle to make as big a mark in traditional engineering.
Hence, "Brahminical DIYer" is a contradiction in terms, unless your DIY is in discovering new proofs for Fermat's last theorem or something. 😀

Do you listen to hard rock or any other type of music which has hard drumming with sharp attack? Does this amp handle that kind of music accurately? I've once heard BAT monoblocks through Dunlavy speakers, but I didn't think it would compare with good solid state on this front. Same reaction to Cadence valve amps played through Cadence ESL-hybrid speakers. Maybe I was wrong...
And I love that wood finish. I think you valve guys have cottoned on to this idea of wood for cabinets much earlier than we solid state types. 🙂

Is this point-to-point wired, or did you use a PCB? Never having done this point-to-point thing, I find the idea scary. Is it very difficult for a beginner?corbato said:Stargrounding and short leads all around. No fancy caps. Generic MKP's and Carbon resistors. Wirewound Pots. BEL EL84+ECC82 and Mullard EZ81.

Re: Re: Re: Re: Made in China
I kow I know some very well heeled individuals who opted for bose however part of that decision was WAF. hence I my next goal is to build a small system that is just as attractive but better sounding (after considering a lot of options from SS to Manger to TB I have boiled down to Jordan JX92 coupled to a 5-6" bass unit)
the bass unit i am considering is a 160mm AL unit made in China for ALR (previously known as ALR - Jordan). it will take a while as there is no commerical interest to any of the parties I am tryig to arm twist / cajole. Just to be sure I have enough to go around I have asked for 25-30 units. I need 10 (5 for me and 5 for my father in law). once i get prices etc. i will post on this forum. if you guys are looking at 5 each then we'd need more ashok, tarun, george, etc... let me know if you guys would be interested in this 160mm unit. i expect prices to be in the range of US$15-20 each.
i intend to mate it with a JX92 ther ther options would be the Vifa D25AG35 or a metal dome SEAS unit or if you guys are interested I can ask ALR for matching tweeters too. let me know.
BTW can you imagine the looks i get when i carry my own groceries, clean my own bath, type my own letters, etc.

This is what I made for myself a few months ago. Cost me very little. I know I know..the wood work is horrible![]()
Ashok,
The amp really looks good. Do you still get the high wattage carbon resistors. In the early 70s I used to purchase the components from a shop in Sakchi, can't remember the name, fat guy with specs. Which shop do you buy your valves from.
I think I will give the valve another try after finishing the JHL amp. I am very tempted to visit Jamshedpur soon to listen to your amp.

PS. I called you twice at your home, a human non recorded live voice tells me you are not at home. How does he know before I call...!!

Tarun: Excellent thoughts. You will be able to sober up some of the mafiosi here
..Is this point-to-point wired..
Yes p2p. Much easier then PCB. Gurus at the tube forum swear that it sounds better that way.
...hard rock...
This amp does'nt handle that stuff well. Jazz and classical sounds just great.
...wood for cabinets...
I'm collecting parts for a JLH Class A. I want to give the same wood treatment. Something like this.
Navin you recall those low-wattage fullrange Phillips drivers? Are they still available?
I've emailed something to you.
Except the power supply where I used high wattage wire-wounds, resistors elsewhere are max 1 watts. Yes I buy them from the same shop in sakchi (pandey). Tubes I buy from other shops.

That humanoid is our servant. He did inform me that that one "hamshu" saab called up from Delhi 🙂. When are you planning to come?
