Sencore CR70

[tvcollector]

I just obtained another one of these off Ebay thinking there was a socket issue with the one I've had for a while..

Well testing the same tube with both of them, the new one I can't get cut off to move at all, as with the old one it will go into range.. The shorts range is different between the two.. When I switch over into Rejuv modes with the new one (without it hooked to any CRT, the breaker will trip powering off the unit).. I notice there is no buzzing noise indicating it's doing it's job.. Any clues?
