Heathkit GR-53A color TV

[Tomcomm]

Ah-Da.........The lastest roundy I seriously investigated was my Dad's CT4 in the late '50's. I was completely unaware of the evolution of tube color tv into the early '60's which your Heathkit seems to be. I agree with you, it ain't worth the effort. But you could go direct video into the video cathode follower, video delay line and presumably chroma demodutor and CRT drivers. You would leave the sound and sync circuitry driven off the tuner/IF as original, just a thought? By the way, what RCA is it a clone of?.........Tom
