Yes, 260x112mm and distance from outputs must be 96mm.
Copy that....
heatsinks on
still thinking I could make it a smaller 2-channel amp instead of a monster mono
nice.. i love your heatsink....😉
Mr. Mile which schema for PSU are good to go for this amp? i'm confused which one is preferable to all diy freinds? 😕
from my personal considerations I would suggest
50+50V trafo...with 80V caps
or
two trafos, 30+30V, 30+30V..... 60+60V(series connected)....with 100V caps

ehm. more like this.
and why do the +/-110 Version only have 15.000uF pr rail. and the +/-96V Version got 30.000uF pr rail?

Pcb is this the end?

schematics principal is what is important,but you can take that as a minimum ratings. you and anyone else will anyway put in the psu what you want or what you have. i can't believe that so many of you people wish to let all the others that you have discovered warm water by claiming that psu capacitors should have larger rated voltage and capacity,like no other knows more is better and that size matters? calculate output amplifier current and multiply by 3000,that should be more than enough even for hi-class power amplifiers working in ab class,so hope it wold be enough for any PA builder's concuisnes.

look at whats available, spec sheets and prices 😱 and you will know why
even those values may be .... 😱
well, Kemet and Epcos 100V, 22000-47000uf seems 'affordable'....and big
for higher voltage you could use multiple smaller caps like 160V, 2200-4700uf
Im going from my own 'local supplier'
your supplier may have more options

Nice work, I must check.

+/-110V version is for mono, +/-96V version is for stereo 🙂

i would use few 160V can type caps. say f.ex 33.000uF. they have a lot more max ripple current then multiple smal snap-in caps. therby also lower ESR.

Of course it is better to use a 160v capacitors, but for many members they are inaccessible and expensive. I offered an alternative to the commonly used values 10000uF/63V. Me personally the most suitable option to 10000uF/100V.
