moe29,
>> hmmm.... family resemblance?
"Touché" ; well thanks, but I have to confess, this photo inspired me
for my A-75, thanks to Nelson for his wonderfull design.
It would have been easy if such heatsinks were available...
Regards.
I hope the remaining work to fire the two channels will be easy ;
at this time I have 350 hours invested in this project.
Regards.

Almost finished, I have no more silver solder to wire the WBT's...
Time to rest before firing the finals...
1* 70 C temperature security on each channel sinks.
I will probably add a 12 volts remote standby relay ; and thats all.
Regards to all.
PS: See you when music will flow!

temperature Mosfet 52 degrees Heat sinks 45 degrees
and perfectly singing, wouah !!!!!!!!!!!!!!!!!!!!!!
great change from the NAD C350
I am so glad, time to rest ...

Alain, the photos from inside the amp where good... the full view of it is amazing! With it's cover on this thing is going to look incredible!
Does anyone know where I can get heatsinks that will fit a multiple of T0-220 packages on them? I have to use a few of them and using individual sinks is time consuming and looks quite messy.

eeka chu,
It works.... speaking od "El Diablo"
Look at these for 2 To-220
http://www.thermaflo.com/bin/stddatasht.pl?Pnum=824302b00000
But you can use watever profile you want from alu bars, angles to mount
several TO-220 in line ... there are profiles for clips mounting also.

I made a mistake :
>> with 67 mA bias, on 0.47 Ohms sources resitors
it was 67 milli Volts on 0.47 Ohms sources resitors
Ultimately when all will be set, I will reach 75/78 milli Volts
for 2 amp bias by channel...
I expect keeping 50 degrees max on the heatsinks...
Note the fan was at minimal speed, and 7 volts supply.
