Default Re: AVO VCM163 - Some faults I have had


I only have the transformer. The guy who wound/tested them was not aware of any changes that occurred while he worked for AVO. I suspected the capacitors were there for electromagnetic immunity considerations. It might be worth checking the 163 with a pair of "Y" capacitors added - Line to Chassis and Neutral to Chassis - say 4n7F/250V.

I've attached the file for the transformer test.
