Then I have to cut all the connections the coil is wrapped on a plastic bobbin if I check resistance with connections on it will seek ground but with connections off there is no path to ground. The only ground is the .001 to ground I checked already.

you dont have to cut anything

measure the resistance between pin 7 of V1 and pin 2 of V2, it should test very high, if not infinite in resistance.

That is the most important thing to test.

It measures 23k and those coils did measure.1 ohm each.

seems OK, for reference, the same test on L5 should test about the same IMOH, if there was a coil short, the reading would be low.

So what do you think of the idea of a cap being a cushion.01 ?

or that 800pf?
but if it is one of those, as mentioned the alignment will be disrupted if replaced, so damned if you do or don't it seems.

your best way forward may be to rig for direct video input.

I don’t think it’s the 800pf because there is no power source with it removed from pin 8 as long as the 6.8 is connected to the 8.2 and then grounded that’s when the voltage is lost
