She's a runnin, kinda


Well I got that 1966 Magnavox combo powered up tonight.. I recapped the entire electrolytic plethora on this chassis the last 2 days. What A PaIn In The ***!!! Who were the elves that wired this chassis, the filters in this set are buried! And the chassis is totally compact compared to the RCA chassis im familliar with. But anyway this set is full of gremlins!

First and foremost (the concerning part), when the raster comes up upon startup the horiz hold is way off and the left side of the screen is shrunk in an inch. Will stay this way until I start adjusting the horiz hold a little, then you can hear the set come in and the left comes back out, raster gets brighter and then I can stabilize it. Good bright raster and plenty of contrast and focus. If I turn the set off and right back on, same scenerio, horiz way off and left side shrunk. I move the horiz hold dial far left and back to where it was and problem solved..

That may or may not be related to the 2nd issue. The Raster after 10 minutes of use gradually darkens, goes out of focus, shrinks on both sides and a little on the top and bottom. If I turn the brightness up picture blooms bad and shrinks worse. If I turn the set off and back on over a minute period, problem solved except the movement of the horiz hold dial to get the pic back into sync.

3rd issue. really bad pincushion top, bottom and sides of the screen.

4th and last issue, Colors way off, but im sure this is due to a flaky demod and agc sync seperator tubes. I should have this fixed soon, (also completely deteriorated bakelite sockets on the x and z demod tube locations.

Any help is greatly appreciated, and you guys are always the best!
Thanks!
Shawn
