Default Re: My first valve radio project - Philips 462A

Assuming that everything we've been told is true, I think we're reaching the inevitable conclusion that the mains transformer is faulty.

You could try selecting the 220V setting, inserting the rectifier, checking the on load heater voltage on the rectifier and if OK checking the HT voltage across the smoothers.

This isn't a long term solution though.
