The 1947 RCA 721 TS is still soldiering on with it's original chassis mount electrolytics. It is coming up to a year and 7 months since my minimal rehabilitation. The axial lead 20ufd electrolytic used for audio output plate and screen bypassing was replaced as it failed my leakage test after reforming. To remind all, two resistors, three tubes, fourteen paper capacitors. Recall I left some of the paper capacitors in if they did not upset any DC levels.
I expect it has close to 1400 hours now.
CHCH TV channel 11 went on air in 1954 and their daytime peogramming in HD are retro programs from the 50's thru the 70's. Oddly, the stations do not multiplex up here probably due to the Canadian media monopoly which favors cable and satellite over terrestrial television. Even the CBC tried to abandon terrestrial TV but failed and only run minimal services over the air.
Anyhow CHCH which appears to be about the last independent terrestrial broadcaster in Canada uses the original 1950's logo mascot. I captured a snapshot off air on the 721TS a few minutes ago with a snapshot from the web.
