Not too much time to work on this tonight, but I did discover that the plate voltage is pretty much missing from the clipper half of the 6sn7-sitting at about .3vDC when it should be at 11vDC. The voltage is supplied by a 330k resistor, the supply voltage is 215vDC on one side of the resistor and .3 on the other. I've tested this resistor a couple of times, and it always tests at about 340k- a little high, but no reason to shut out voltage like it does. But having a freaky clipper certainly would explain the sloppy sync I am getting....

In other news, I emailed the screenshots that I have been getting of the set to the original owner, who only grew up with it in his house and never saw it running in the fifty years he has had it before giving it away. He was pretty pleased to see it working at all.
