I purchased a board and I have the diagram. I guess I could go through and read the diagram to create a BOM, but does anyone know where one might be already published?

Here is what I have so far:

YAHA BOM

NJM4556 Opamp
LM317
ECC88 tube
2x 47k resistor
2x 220uf Cap
2x .1uf Cap
2x 4.2R resistor
2x 22R Resistor
2x 1meg Resistor
2x 1k resistor
2x 4k resistor

Pot
Input Jacks
Headphone Out Jack
Power Jack
Enclosure

Am I missing anything? Also, can I nix C2 like on the Cmoy?

Oh and a 12V power supply

Where do you get a YAHA board from, anyway?

Let me know if you want one, they made me buy 4.

juniperlater, a good place to start would be over at Headwize:
HeadWize: DIY Workshop > The YAHA amp thread part 2

Here is the start thread. Might contain a bom, but likely contains more design info than you'll need. Read with caution!
HeadWize: DIY Workshop > The YAHA amp thread part 1

Enjoy!

Yeah, I am a little over my head, but the schematics seem to be very close to a Cmoy + tube config. I think I have everything ordered and since it is a printed board, I am sure I will figure it out.

 

[synaesthetic]

As nearly as I can tell, it's a basic cmoy type design with a tube stuck to the end of it. =P

Dang, the shipping on these PCBs is painfully slow. I still can't guarantee the accuracy of my BOM on this.

I am finally getting around to working on this. I am populating the board, but wonder what kind of heatsink does the LM317 need?
