Oscillator off in RCA CTC-11?

[Phil Nelson]

In my RCA CTC-11, all of the channel frequencies seem low by about the same amount. The best tuning is found if you nudge the channel selector down a little and hold it. The difference seems present for all channels. This is outside the range of fine tuning. Adjusting individual oscillator slugs for a couple of channels didn't do the trick, either.

I suppose tuner components can drift with age, like anything else. I'm wishing there was a trimmer with a big red label called Master Oscillator, which I could tweak to move everything up a little.

The TV has great reception and stability otherwise, so I don't want to degrade that or force a realignment, which I'm not equipped for. It's more one of those annoying little things.

Ideas? Here's the tuner schematic for those who like to follow along at home.
