Default Re: Ferroresonant Cnst V transfmer; Faults?

@ Turretslug re Variac; using a 100W filament bulb as CVT load, that gives a light-meter reading of 7600 lux when the CVT is connected directly to the mains supply compared with 7400 lux when the CVT is fed via the Variac (8amps) set at 240 volts. I didn’t check the mains voltage at that moment. So, in that particular test, the Variac “effect” could well be measurement error?

@ Skywave; thanks for that insight on the use of 4 by 2” Al. I’m glad it’s not just me being weedy. Let me get back to you re the caps.
