I get some MG-6330R and MG-9410R. They look promising, with the 2A/100V DC SOA.

What about your pcb?

Any more comments??

Under construction. But I already have the heatsinks, and the enclosure.

Any more comments??

a small lytic at each output ?
(but means you may have to increase the ground area)

board looks great 🙂

Q6/ BD681 is placed too far on the heatsink, which means poor thermal tracking. Would be better to place it somewhere in the middle of the heatsink but you don't have the required space on the PCB. Unfortunately you would have to redesign the whole PCB. The best solution would be mounting it directly on one of the output transistors. 🙂

From emiter to emiter 2SC5200/2SA1943 is 47R/2W not 10k/2W.
Can you made pcb for http://www.diyaudio.com/forums/solid-state/236256-retro-amp-50w-single-supply-2.html

Got that Mr. Mile, i'm correcting it now..
Sure will make that one too just give me some time...

 

[wiljj78]

Now corrected...
