I just finished replacing resistors and correcting the capacitor errors of the guy who worked on it before I bought it. It sounds nice on my work table on AM. I fed it signals with my signal generator and all of the other bands are receiving, very good news. Now to clean the chassis, repair a cracked tweeter cone, and align it. I'm glad it does not have as many trimmers as the 38-116 I restored.
Using a VTVM, I see tweeter output only once the volume is quite high, so I should also investigate that. It may be designed that way, but it never hurts to check the circuitry and study the schematic.
The audio shorting switch, like the one on my 38-116, seems to always be in the shorted position. I may take the dial shaft mechanism apart, but think the shirting switch arrangement is a bad design, so may just cap that wire.
I'm still missing the hooded dial light assemblies, so will search for them (rather than repair them, the other guy just threw them away...).
