Another one saved. Picked this one up (delivered to me) for $10. Probably not even worth that. The glue holding the front panel to the curved side structure was completely broken so the cabinet had to be disassembled and re-constructed. I've done very little with toners in the past so this was a learning experience. Not a perfect job, but just ok. Interesting that areas of the sides had absorbed more stain or whatever they used originally causing a bit of a blotchy situation. I re-stuffed the caps but replaced all of the dog bones with modern resistors. Didn't think the radio warranted the work of trying to salvage the dog bones. As you can see, there was a lot of rust so I opted to take the easy route and paint.
I did the mods that Ron recommended by adding a gimmic and re-wiring the cathode circuit. The radio works ok but needs a good antenna. When aligned per the instructions, I find the sensitivity at the low end of the dial to be much lower than the high end. The instructions say to adjust the antenna trimmer at 1400 kc. Sensitivity at the low end increases greatly if I readjust the trimmer with the dial set at 600. I compromised and set the trimmer for best signal in the center of the dial. Is this typical or is there a problem somewhere? Does the gimmic cap affect this? Ron, your experience please! This radio had the attachment on the 1st detector tube socket for a shield. I could find no photos of an 80 with that shield. I put one on anyway.
I miss AGC on this radio!
