Re: Technics SX-FA1 no load. Blue screen.

35volts AC once rectified produces around 50volts DC which is normal. On load this drops a bit but not that much. Whenever you measure AC at a transformer the DC volts will be around 1.4x that voltage off load. There isn't an easy place to measure the DC …
