Edd and others have been a huge help in steering me towards a solutione. I have other issues to fix, but the tuner is working. This was the one that started the scope discussion and the scope did help some, but a hunch was the real key. T2 had obviously been messed with a lot, but I checked and checked the wiring and it seemd ok. I convinced myself that the leads on the secondary of T2 might be reversed and if so, that might put the RF signal in phase with the oscillator and kill the tuner. Changing the leads around was the last thing I did, would this in fact be a cause?

Hey, it worked for me, (well-Peter actually, but you get the idea.)
