If you have a variac you can connect it to the secondary and start at zero while monitoring the rectifier filter and bring the voltage up slowly till you get the proper DC levels. 9.3V and 5.1 volts. Then measure the AC. Do you need to know where to connect the AC? Where to check the 9.3 and 5.1? ******************************************************************************************************************* Since 1972 Jim Myers Telrad Electronics Fort Wayne, Indiana Bob@Bobs tv wrote: > Sony > STRDE335 > Stereo > Would someone know the secondary voltage on the standby > transformer that's not available?
