Color preferences?
Usually green is the least expensive, but I prefer red or blue boards.
I can go with a green board just as well. 😀
I made an attempt to create a Digi-Key shopping cart that contains:
- ICs, are the opamps LM4562 and OPA627 ok for this?
- caps (except C1/C5 as i believe my Mundorf M-cap 2.2uF will do?)
- diodes (edit: D7/D8 were missing, add two more)
- heatsinks
- resistors that I don't have on my shelf
Invalid Request
Any comments and corrections are welcome. Remember that this is not a complete list of items, just a starting point. E.g. Digi-Key doesn't have Alps pots at all.
Edit: I forgot to mention that the item quantities are not optimised! There's more than you need on some components...

I would like to order my board in the same green color of my Pass B-1 board if possible
thank you
thank you
Yes, I guess both my B1 and Pearl 2 are green, but makes me no difference if everyone wants to go with another color.

On wayne's PCB, I'm assuming R17 and R35 marked 47 ohm get jumpered? They look like they can be used to drop voltage from the FET rail to the op-amp rail ...

R35 & R36 ... sorry
I would love to get 2 boards, one for the standard build and one for experimenting. 6L6 seemed to indicate there were a number of configurations possible and I wouldn't mind having a play.
I like black PCBs but really I am happy with anything.

BIG order from Mouser and Digi-Key today! I'm working on this, 2 other Class-A headphone amps as well as modifying my Hammond T-412.
Anyway, got the PCB stuffed and test fit it into the chassis ... so far so good!
Where are you finding the Toshiba 2SJ313/2SK2013 transistors?
Thanks.
