selenium HV rectifier

[wa2ise]

I wouldn't have thought that any TV set would have used a selenium rectifier for the high voltage. Selenium rectifiers tend to be leaky and lossy. And tube HV rectifiers are fairly cheap, but do require filament power, which is always gotten off the flyback circuit. Submini HV rectifiers, IIRC the 5642, are small and can do up to about 10KV, not enough for color TV though.
