I have determined that I have a shorted 10mmf capacitor going from pin 9 of the osc to ground. Resistance readings for pins 9, 8, 6, and 3 should be infinite... and yet I get 200 ohms on 9, 6k ohms on 8, 7k ohms on 3, and 8k ohms on 6. After studying the diagram, it seemed pretty clear that the little cap at pin 9 must be the culprit.
However, the damn thing is so far in there that I can even get my little cutters in there to get the cap out. I think I can manage getting a new one in, but getting the old one out seems to be a challenge.
For shits & grins, I tried calling Louis Stangle in Longview, Texas... he's the guy that repairs tuners and I've heard good comments in the past from people here at VK. Unfortunately, all the numbers listed on the site are disconnected, and there is no email address listed in the site. From what I understand, this man is in his 70's. I certainly hope he hasn't expired.
On a longshot, I tried calling Moyer's to see if they had a tuner for it. They can really surprise you with some of the old stock they've got, but didn't have what I was looking for. He said most shops sent tuners off to be repaired instead of ordering new ones.
Sooo... I'm back to trying to figure out how to get my fingers in there to do what I need to do. If I could at least get one side of that cap disconnected, I could verify my suspissions about it being shorted.
