Re: AVO VCM163 - Some faults I have had
Martin
261 Volts is within UK tolerance. As the testing was done with zero load, the only current was magnetising current and it didn't even register on my ammeter. Quite apart from this, I am looking at the secondary voltages, which will always have the same relationship with one another. I suspect that at the time the 163 was manufactured the choice made regarding filtering of the input may have been 4 X 1uF was cheaper/easier to fit/readily available than a 400V ac capacitor.
There is a screen on the transformer. Has anyone tried seeing how effective it is?
