Predicta Holiday - First power up attempt

[madlabs]

Hi All,

Whew! Busy fricken' week here! Not much time in on the Predicta this week but I do have 40 gallons of apple cider fermenting!

The thing blocking the A11-12 audio adjustments turned out to be part of the slug is broken off. Crap. What are the chances of a repair? Or should I just start looking for a replacement? I'm still having trouble getting good sound with no 60 Hz hum. The buzz control doesn't affect the hum at all. It is driving me crazy and is the biggest thing preventing watching the set being fun. Maybe C34? Or some other ceramic cap?

On the upper 1/4 to 1/2 of the screen is (sometimes) a whiter area. It moves with contrast/brightness changes in whatever you are watching. If the scene is darker it disappears.

The vertical linearity control does nothing. Neither do the vert centering or horiz centering up on the CRT.

And a bonus non-electronic question: Ordered the Novus polish. Do y'all hand polish or use a small buffing wheel? I may have to break out some sandpaper for some scratches.

Thanks and sorry for it being so long since I updated the thread.

Jonathan

EDIT: Forgot to add that cleaning the tube sockets and pins in the tuner seems to have resolved the horizontal hold issue, it is locked in quite well now. Is it likely cleaning the sockets was the fix?
