Hi Jens,
Well, if you read the thread where I posted the pics, you'd see that it all started because I had bought the 64-0-64 transformer and was looking for an amp design I could use it on. The Superamp was suggested and the rest is history. As a matter of fact this thread sort of got started because of my asking questions in the Leach clone thread about your boards.
I'm into it now so I'm going to stay the course until it is finished. Still hoping that it will sound great. Time will tell.
Blessings, Terry

Part numbers
Do you want all the digikey part numbers or just for power caps.His parts list has digikey part numbers for alot of the parts.The other you have to search for .I didnt get all my parts from digikey ,they are expensize on alot of stuff.The only didgikey part number for heatsinks that still around is the one without holes.They do have replacement types I think 14 or 15 us dollars apeace .The ones with out holes are h-type.You can get transitors
from on-semi for free.11.00 dollars for shipping.I can give you a list of all the parts I got from digikey if you want.I can take pictures if you need them .I got most of the caps from ack radio , still havent received them been 4 weeks they just shipped friday.Way to slow.I got like 30 12000uf 80v caps snap in .If they turn out to be good I can give some up cheap if people want them ,I could send someone with some expertise to test them, then we know that guy onbay has good stuff.We could then group buy the same lot I got from him.

What voltage is your caps rated at?
Only 125V. Doesn't seem to be a problem. Used it like it was a PA a few times, driving it really hard for hours on end. Heatsinks got a little warm to the touch. No fans. Sounded great in a big hall. Can't play it over 60 some watts in my small room without hurting myself and others. Just TO3's bolted to the outside like in the pics previously published.

Mmm, did i mention i am building 4 extra Alephs, considering 2 Zen-X's. Still need to make 1 woody GC. Still waiting for the Dutch group buy for a load of IRFP's. And i am working on designing the XVR1 board. Collecting parts to do the Pass Monster when the first 3 sets have been tested and the final circuit is available. In a month or so i have to do a tube thing for my Johnny Guitar Watson neighbor. Just made a set of PerAnders headphone pcb's. There is a Philips alloy professional CD device waiting to build in a proper casing, have part of the electronics ready. Thing came out of one the first series CD-players, believe the alloy platform is still produced for topnotch CD rotators.
And i am renovating the 1935 orphanage i live in.
Can someone shoot me, Please !
A high voltage cap group buy sounds tempting, gimme gimme.

Only when they sink !
I read it as that i am quite busy for someone without any decent skills.
Maybe it helps that at 8 i learned to operate a lathe at my dads place.
It spent some years at Alloy molding companies and aeviation plants before i devided to draw ships that sink and subs that float.

Only kidding, Bob, and you should know.
I checked the Ocean engineering program at MIT once, exactly the same classes as overhere.
After my first classes on Laplace equations, Fast Fourier Transforms, thermo dynamics and differential equations i noticed how interesting audio electronics became.
Nice to meet a fellow boat guy on diy audio.
