G8UWM,

Thanks for your reply. Once again I checked voltages and the circuit seems working as designed unfortunately.

The transformer outputs AC 373V (average, w/ following recitification unit), and the recitification unit outputs DC 523V (w/o voltage doubler capacitors), and then plate voltage is DC 1055V (w/ the capacitors)

1055 is almost 373 x 1.4 x 2.

According to the schismatic of PS-510, a power supply unit of TS-510, the transformer is designed to output 340V 0.64A.

So maybe something is wrong with my transformer or hopefully some other parts of PS-510 is wrong and so transformer over-works.

How do you think?
