Interesting, I'm out the 1.2meg resistor here otherwise I would try it now, I'll order some along with the new lamps, and try the resistors first, if it works, I'll leave them out.
I got the channel changer on the remote to work, but only after it warms up for a few minutes and in short range. The problem was one relay wasn't staying engaged. First of all the contacts on that relay were a bit dirty (must have been used more.) Secondly, all those 6EV7 tubes are weak (and I don't have any replacements here, so I'll have to order all 3). Thirdly, I did improve it a bit by trying to align the remote receiver. I was going to follow the procedure in the sams, but then my signal generator wasn't working (I have mostly all old partially, or not at all, working test equipment, one day I really should sit down and try to fix more of it). So what I did was to hook a vtvm directly up the grid of each of the 6EV7 tubes corresponding to the button on the remote I was pressing, and then adjusted the corresponding coil for maximum voltage on the meter while I was still holding the button on the remote down. It seemed to work. But I'm still hoping I can improve the range of the remote with new tubes. (it's only about 5 feet now and less than 2 to change the channel)

I just swapped the 6EV7s so the strongest one is connected to the channel changer relay, and the really weak section of that tube that was controlling the channel relay is now controlling the tint. For some reason I can still control the tint at a little over 5 feet away, but now I can also control the channel at that distance too.
