TUAC TD500-C1 mono amplifier

TUAC TD500-C1 amplifier board

The simple markings on photo does not have the Anode and Cathode marked.

Please reload the page as I have updated the last image.

There is no need for a 630V cap in that position. The max voltage difference on the amplifier board is about 120V so even a 250V cap gives you massive margin.

At least you can see the polarity of the diodes and the zeners are BZY series. The wirewound resistor at the end has been massively upgraded with two in series

You can also change all the power transistors to MJ15003 as they are easy to get

Was that 56v without the amp connected as voltage will drop with it connected

Thanks for the tip :)
While I wait for more zener diodes i am thinking a bit about measurement points and since I have no manual or description, I'm guessing a bit here..I can measure the output emitter resistor, at the marking with a blue ring?
