Channel master

[newhallone]

I was at my parents and I grabbed my Grandmothers Channel Master portable 1966 that she used at camp to watch her "Stories" I never liked it but alas it has grown on me. So I took it down from the attic of the garage because it was getting covered in wood shavings. I took the Channel Master dust cover off and blew it off with the air hose a little. It used to work but now I think there is a power supply problem. I got the sams for it the other day and looked it over and wow. A billion caps! the circuit boards say Sanyo on them. I guess on something like this do the main caps and then replace only as needed down the road. I have visions of a multitude of bulging caps like I remember seeing in a 70's Sony video camera.

Interesting catch. I know whem ym maternal grandmother passed away, she told me when that time came, I could have her early 1960's RCA set. I figure it was made around 1961/62, it had no UHF tuner. Alas, I didn't get it, don't know what happened. Still would have made a nice room TV, with digital coming, the converter box would take care of the lack of UHF.

I remember watching shows like "MASH," "All in the Family," "Chico and the Man," and so on with her when I was a kid.

I would replace the electrolytics in the power supply and then see what happens. Many of the small caps may still be good, unlike the paper wax caps and "bumblebees" used in older tube devices.
