Hi!


Yes i had some spare time today, to hot to go outside here in Amsterdam  :)

Schematic update:



And this is the Power Section, build on a CPU heatsink, everything short wired.



Almost done, only the ground and de +bar on the bottum side.



Not yet cleaned and missing two wires like i expland, row-01 (ground) and row-18 (+)



Shoot @ It!

Regards,
Bram

@Blackdog - I've seen 2SC5200 in audio amps.. OK you twisted my arm  :-DD Digikey has them at $2 ea. if I buy 10.

Thanks, I am looking forward to see your perfections on this design sir - great work as usual!

blackdog:
Hi Cliff,

Do not order or buy anything, let me first do some tests...

Circuitboard cleant with IPA and a old toothbrush, i hope is stays this way  :-DD


Heathsink mounted with a Ty-Wrap.

And now its time to doe some work!
Later more.

Kind regards,
Bram

Cliff Matthews:
Looking good!  :-+ (Q6 needs a label correction though, details details..)

HoracioDos:
For those who might be interested. I hope I didn't make any mistake while copying the schematic.

PS: I've fixed the schematic around 6.2V zener as it will be seen next
