Started the ordering process. Here is a Mouser project cart Mouser Electronics
What is missing are C6, C7, C10, C11 Those Nichicon caps are not in stock at Mouser, you may be able to find suitable subs. I just went to Digikey and ordered all of these caps, which they have in stock. Adds a bit for shipping and sales tax, instead of one stop shopping.
The numbers in the Mouser order are for a Stereo build, so twice as many parts as the BOM Marc has posted.
What is still needed, would be tubes, sockets, transformers/PS.
Combined Mouser and Digikey orders with shipping is around 110usd. I found matched quad sets of EL34 tubes 70usd, Pair of EEC88 tubes 25-30usd, Hammond 1650N output xformer pair 263usd and going with separate power, spec a Hammond power xformer a pair of 370HX (covers plate, bias, and filament in one package) 271usd. Six ceramic sockets about 20usd.

Would someone with more tube knowledge please confirm for me if the Hammond 370HX is what is needed for a EL34/EEC88 build? Is it too much or too little? Hammond Mfg. - Universal Primary - "Classic" Power Transformers

David the 370LX would probably be a better choice if you are making a stereo unit. The 370HX secondary is 6.3V @ 6 amps, each tube draws 1.5 amps, without considering the draw from the preamp section. The 370LX is 9 amps giving you margin. Also, you might consider the Edcor CXPP60-4.2K it is almost half the price of the Hammond 1650N.

Bonjour,

Still more people confirmed that they received the PCB :D

@ckwong99
For technical question please go only to EL84 Amp - Baby Huey I will answer it here since I am already posting : The feedback input can be used with a connexion to the secondary of the output transformer in case of instability, in my case I have not used it :) It can also be used for a differential input in this case use the same value like the input ones !
