Ok, thank you so much for your advice...If I supply this amp up to lets say +/-70V, will it give significant sound improvement? Now I feed this amp with +/- 59,5 volt, and I like the sound very much.
Best regards,
Arif

Default Thermal Coupled

Hi...
This my PCB design of SR200,
Are all these small TR need to thermally coupled?
I arranged them like that so it easy if it is need to thermally coupled

It is still need to be check again & if it its a bad design I will redesign again...

Regards

Dear Apex,
I have 2 pcs of 4,7 uf Jantzen MKP, is it possible to use them instead of 10uf (C1), considering that now I use very low budget 10uf MKP. What is the result? Or should I have to find another 10uf MKP. It's hard to find good 10uf MKP in local suppliers.
I also have 2 pcs 2,2 Bennic's and 2 pcs Solen MKP and I plan to use them instead of 1uf (C4) for the same reason above.
Thank you so much.
Best Regards,
Arif B

It's possible to use 4,7uF instead 10uF in audio path, but no need to change 1uF in DC servo circuit.
