Hi all could anyone help me this is my first post here so please be gentle:D. I need to find the secondary voltages of the mains transformer, the caps in the power supply are 63v which suggest say around 40v maybe. But the voltage at Q215(PNP 2SA970) is 54.3v on the emitter which puzzles me a little, can any body help me please.
