Thanks again Terry. It seems to be "functional" although the band calibration is off. I'll address that later. The RF controls were very scratchy, at least RF-1 was. Spray cleaner didn't work so I removed them to open them up for inspection. RF-1 pot is defiantly bad, the other cleaned up but here is the problem. RF-1 is marked with 20000 (assuming 20k) RF-2 is clearly marked and measures as 25,000 ohms. The problem is the schematic shows both of these controls as being 200 ohm! Why would there be such a huge difference. They physically and brand are not the same so it is safe to assume they were replacements. So do I put 200 ohm or 20k ohm pots back in? Both are carbon wiper, but audio or linear taper. How is that determined?
