Hi Angeltech
greetings there is no schematic but files are correct problem sourcing small
transistors and 7.5N cap WILL try it in the future
warm regards
andrew lebon

 

[angeltech]

maybe series or paralleled caps will do, for small transistor if i'm right you mean the KTC3200 low noise high voltage NPN not available here too heheheh

If I could source the part I'll give a try this amp, But I wonder how this amp work seems no oscillator driver for voltage shift, like H900 does.

Also specification of the choke coils not specified any Idea?

picture will do I think hehehe...

Regards,

Angeltech

Hi Don
greetings nice to hear detex HD class is working use IRF260 mosfetsin place of IRF250 and MJL trs in supply and outputs all my projects paused as
my teaching schedule leaves me very little time for diy working on lab gruppen
driver stage is working excellent quality audio
