I found a beauty of a vintage television for $10 at a local dump shop yesterday - a 19" AWA Radiola P2 slim "portable-tabletop" television from 1966. Does anyone have a circuit diagram or service manual for one of these sets?

Also, upon test powerup yesterday, I ran into a problem. I could hear the EHT slowly come up - however there was no raster at all (even after adjustment of the brightness). When I switched the set off though, there was the typical CRT flash on the screen and a prolonged spot of afterglow.

Could this be an issue with the CRT, or something in the EHT section? I'm wondering if it's the 1B3GT half-wave rectifier, since it is in line between the flyback and CRT anode.

Hi Chris, another nice save!

The 1B3 is not likely to be at fault. My bet would be the two wax caps (or more) in the line output stage on the boosted HT supply.

I have all the service info for these sets. I'm having internet issues at the moment so I'll wait till I a reliable connection before I do anything.
