Hi Steve, Thanks for the info. I don't have a lot of 12BA6's or 12BE6's in my spare tubes collection. Still on the to do list is cleaning the tube sockets. Hopefully the 1K CTS pots will arrive on

Check the other resistors in the meter bridge circuit. They can drift out of tolerance. Also, check the no-signal level of the S meter with the AGC off vs AGC on (with no antenna). I had gassy tubes

Thanks everyone for the tips on repainting the cabinets. When the weather is more favorable for painting;I'll work on repainting the cabinets. Currently working on the R-4B. It has a bad receiver

I'm looking to do a little restoration work on a new to me 4 line. T4X, R-4B and MS4.? I've read Mark, WB0IQK, article on the WB4HFN site about cabinet repainting.? Problem is I can't seem to find
