That got to be for 2 channels..
Yes it is.
Hi kodabmx, I went through the stash of the tubes I have, and I see a lot of 6N6P and 6N2P. Can I use 6N2P instead of 6N3P? Are they considered equivalent? If yes, I would be interested in the board. Thanks
They are not equivalent nor are they the same pinout. 6N3P mu=~33, 6N2P mu=~100.
You can however use these adaptors: 1pc Gold plated ECC88 6922 6DJ8 6N11 6N6P TO 6N3 5670 tube adapter for you amp | eBay
and change the associated cathode resistors from 240R to 1k and it will work albeit with 3 times the gain.
I've made a revision to the board - the cap footprints are all onboard now.

Yes, i know, but i have more than hundred 6N2Ps...
I do too! (do you need any?) But they (6N2) are 12ax7 like-tubes with 70-100 amplification, apparently not what you need here!
So, get yourself some 6N3P tubes while they are still cheap!
No.
You chose the size based on the load you will drive and the LF response you want.
If you use it as a line stage, it could be as small as 1uF if you're using it to drive a tube amp.
I chose 470uF because they are common and give a good LF response on 32R headphones. If I was making one for just my ATH-R70x (470R) I'd use a 47u film cap only.

Have you compared the 6CG7 to 6N3?I now have a board for 9AJ as input (6N1P 6DJ8 6CG7 etc) instead of 6N3...
Whats the difference.
I'd say on paper the 6CG7 is more linear being a 6SN7 electrically.
That's a Hammond box, ya?
As far as the SMPS yes i have to say I like them a lot. Google search for "12V 280V" and you'll get a bunch of results including this one: AliExpress.com - Maintaining
