 They aren't that bad, I've worked on a couple of these, and will work on a couple more that are in the restoration docket. One was a C.G.E J-82 and the other a Canadian Westinghouse 801 Columaire which uses similar circuitry and components but in a Westinghouse built chassis, the next two will be another J-82, and an S-42A. The biggest nuisance isn't the tuning condenser it's the IF cans and the oscillator coil, which you may or may not have to remove to get at some things. These sets are good performers though, which probably explains why there are so many survivors as they were probably good sellers.
