"The Wire" Ultra-High Performance Headphone Amplifier - PCB's

[Wolfsin]

Thinking outside the SOIC

They've been called several things so far but it seems clear that at $2 those PCBs are a screaming deal. The LME49710HA parts would allow wire bending rather than trace cutting.

Owen, I opted out of this go round, but did purchase one of your Bal-SE units in the first group buy. I'd be interested in a couple of the "rework" boards if you end up with any extras..
thanks
John

Hi Owen,

As others have said, thanks for running this group buy. It is very much appreciated!

Please add to my order two of the BAL-SE boards and two of the rework-required SE-SE boards.

opc - I'll go for 4 of the rework boards.

Also, unrelated, I just noticed that the power supply board would also make a dandy CRC filter if the LM317/LM337 chips are left off, along with the associated adjust pin parts, and replaced with Caddock 10R 30W TO-220 resistors.

The capacitor values would be an order of magnitude too small to do anything about power line 2nd, 3rd, and 4th harmonics, but would make a dandy power line (conducted through transformer parasitics) audio band and RF noise filter for general purpose use.

BTW Owen, if you decided to make yet another run on the PSU PCB, I think you might find quite a few takers, especially with the rework-required boards becoming available. It would certainly help make those boards even more attractive.

I know I myself could now use an additional four PSU PCBs.

i'll take a few (3) of the rework boards too mate if any are left and perhaps 2 extra psu boards if you have any spare. paying with cash money for extras =) btw check email, does red indicate paid?

thanks again mate!! this is a serious undertaking and i'm sure everyone is both thankful and amazed at the work put in

yeah but theyde also make the noise performance worse

Please sign me up for 2 of the SE-SE boards requiring patching.

Do you have any PSU boards left? In that case 2 more of those.

 

[MarkB1]

I'll take 4 of the rework se-se boards thanks Owen.

Hi Owen,
May order as detailed in the latest PDF is correct.
Please let me know ho to pay and I will straight away.

I remember you want to use paypal right? Happy to do this.

Thanks for all your hard work, I am very excited.

Owen,

I may take one bal-se board. I realized that the content of the pus kit is very minimal, and I think is mostly an headache for you.

So sign me for whatever is easy for you: 2 psu (board or kit) and 1 bal- se.

Thanks,

Davide

[forsakenrider]

1x BAL-SE PCB
2x rework SE-SE PCB

Hi Guys,

The new system of sending out PM's for payments seems to be working perfectly. I'd like to extend a huge thanks to everyone who has paid so far. You've followed the instructions perfectly, and I've already got the orders packed and ready to send out! I really appreciate the prompt and correct payments!

All the "rework required" boards are now sold out, which took all of 12 hours! I've updated the list and posted it below with some additional columns to cover the reworked boards, who has paid, and what has shipped.

I'll be sending out payment requests for the rest of the headphone amp boards over the next few days, so keep your eyes open for a PM.

I still have two question marks listed on the sheet:

1. Bill Wilson - I have no idea what your order is (if any). Please confirm!

2. mwmkravchenko - Mark - Can you send me a PM or email with your total order? I've pretty much lost track of what you need, and I'm not sure how many extra mosfet pairs you want

Thanks again to everyone for your patience and cooperation!

Cheers,
Owen

Hi Owen,

I'd like:

3 x bal-se boards

and 2 of the psu boards if there any left unaccounted for at end of the day please

 

[forsakenrider]

I guess I missed the rework request, I also didnt seem to make it on the list for the BAL-SE. I still want the BAL-SE even if the rework is closed:

1x BAL-SE PCB
1x or 2x REWORK if anyone is willing to give up one.

 

[particleman14]

Can you please add 1 se-se rework board. thanks!

 

[Narmaraktuk]

Hi Owen,

I'd like 2x bal-se boards please. Psu boards + parts for all boards GB are closed, but I'd like those too if any are left.

Thanks!

Hi Guys,

Payment requests are going out for everyone who has purchased a headphone amp PCB or kit and does not have amplifier kits in their order. They are being sent via PM.

I've attached an updated list with the total shipping weight and the total price of each order. Detailed instructions are included with each PM. Please follow them very carefully!

Orders will be shipped in the order that they are paid.

Cheers,
Owen

Ok, I know this is the 3rd time I'm asking but I'm getting nothing. I would AT LEAST like a BAL-SE PCB at minimum. Is there a minimum order somewhere? Anyway, I'll try again:

1x BAL-SE PCB

thanks.
