Can anyone please suggest an alternative or provide the specification for the Russian rectifier / diode K203A?

Hi Hoppy,

For diode use Ð"Ð"РÐ' diodes like КÐ"203А, КÐ"204, 2Ð"210А, 2Ð"210Ð', КÐ"210A, КÐ"210Ð', Ð"Л 132-50. Equivalent diode exist.

Some diodes which can be used:

Ð"Ч143-800 -> 1400Ð' 800А
Ð"143-400  -> 2400Ð' 800А

Hope that helps,  regards Itsu

Thanks Vortex1,  thanks verpies   
for your feedback, its much appreciated.
I will have to do some work/learning and try to incorporate your advices.
Regards Itsu.

I would like to see your scopeshots of voltage between the ground and sources of your MOSFETs as well as the voltage on the power supply pins of the TL494 IC (measured from the same ground point).
Ideally the scope should show pure DC.
