I'm asking this on behalf of a friend:
Why would there be a ceramic capacitor across the primary side of a transformer for a Ham Radio power supply? Would there be any harm in removing it?
Also, he is trying to increase the plate voltage on tubes after the rectifier. The power supply has a multi-tap primary. However, when he changes the primaty tap from 240V to 230V the rectifier output does not reflect a linear result. The output is much higher than expected. Perhaps the diodes are operating outside their linear region? Any theories?
Thanks.
