One board installed (almost) 🙂 waiting on 3rd set of transistors to be installed (I just love the way they smell when smoking)
If those heatsinks don't keep the diodes cool, then ............I QUIT ! 😀
Someday I'll hear them singing! At least your plywood F5 worked! This is my Karma for teasing you about the plywood.

Looks nice. The heatsink size for the diodes is plenty, but you need to firmly attach the diodes to the heatsinks with some screws or clamps.
acold7dusta,
If you are referring to the resistor next to the caps in the power supply then yes it is an R. It is used to bleed down the caps after powering down.
Christian, The diodes have a little hole that is made for a bolt/screw, the heatsinks have a little dimple/nipple that fits inside that hole. There is no way to put a bolt in the hole. Other than many tiny "C" clamps, do you have any suggestions of what to use? They really do NOT get even warm to the touch.
Thank you for all the nice comments. At this point it looks like garbage to me.

I was thinking you might be able to find some of these:
An externally hosted image should be here but it was not working when we last tested it.
It might work if they can apply enough pressure on the device. If I were you, I would have drilled and tapped some holes.
Oh yeah, sure, make me feel bad. 🙄
I ordered these clips today from Mouser. They are just what the doctor ordered. 4 1/2 lbs./sq. in. otta do it. Should be a perfect fit and won't melt! $0.23 each is worth not having to take the rectifier boards out and drill all 8 holes by hand, metal shavings everywhere.......Oh my! 😱
Thanks for the link.

Excellent plan.
BTW I have started shipping out boards last night and will continue tonight, but will probably not finish due to lack of stamps. Those international orders really clean out my stash quickly. 😉
I send from the back, so those who have waited the longest gets theirs first.

Yeah, and you would have done it right the 1st time .....or the 2nd time.... or the 3rd time.......
but where's the fun in that!

Schnikes!! My boards came in the mail today and they are amplifier jewelry, just beautiful!
Is Tech DIY offering F5 kits that fit this board? Talk about one stop shopping. Cave men like myself are grateful for the support.

I need to request some assistance and don't know if this should go elsewhere.
But, my enthusiasm frequently out distances my knowledge and judgment.
I purchased two ginormous toroidal transformers that may become boat anchors if I can't regulate them down for the F5. I imagine I can easily get by using just one for this amplifier. But I don't mind being silly and strapping the two large mains and having separate boxes for each channel. I can always use them to do some arc welding when not playing music.
What sort of regulation comes to mind and how would I wire it? Any leads would be welcome.
