Predicta Holiday No Picture or Sound

[greggburnett]

Managed to find a decent CRT replacement, and to get the controls (touchy), adjusted pretty well.

I had an annoying audio hum, until I tapped the L16 (Sam's) 2nd sound IF coil 32-4745-2 with my small plastic tuning screwdriver. The sound cleared!

Now, when I slightly wiggle the coil shield, the hum cuts in and out.

I have removed the board (again), and have checked for cold solder joints, etc.

Everything looks clean.

Do these coils have a history of internal intermittents?
