I replaced the following: Q923/2SA1020 Q943/2SC2240 PC901/TLP621 IC101/7809 IC901/STRF6626 IC941/SE135N Now, the relay clicks and the LED lights when power button is depressed. Still no high voltage or sound. Does anyone have a scan of the power supply section? I don't think I'm getting the proper output from the regulator (IC901). Any help appreciated.
