cleaned the tuner now I have issues

[DaveWM]

my B&W maggie console, daily driver.

pulled tuner out, popped out a few of the unused channes strips, cleaned the stationary fingers (super slick cleaner, no silcone etc... used on pots and other stuff) by wiping them with a paper towel damped with super slick. cleaned up very nice. did the same to the buttons on the turret. used the big eraser to shine them up some more. did NOT drench any thing, but maybe a spritz got some were.

anyway put it all back together. Perfect no snow, do not have to find the sweet spot (it was a real pita before), BUT now ever few seconds the pic will jiter, like a lost of sync (both vert and horz). this was not a problem at all before the cleaning so I am assuming its related. I did replace the sync tubes any way, no help.

I checked to make sure the AGC voltage was still at the tuner in case I distrubed the wiring, I even clamped the AGC at the tuner with a variable DC supply, no effect (I could dial in snow with increased agc and it would still shake).

I tried letting in bake by playing for a few hours, I will try that some more and see. My only guess is the spritz got on some vari cap inside the tuner and is causing problem. I will get the B&K 1076 out next and try feeding a IF signal after the tuner to see if I can isolate this to the tuner itself.
