I just got this interesting GE radio model J-100. This thing is built like a veritable battleship.
The most interesting thing is the rectifier. It's an 82, mercury vapor rectifier. It has the most beautiful blue glow inside the plates. The only other thing I've seen with mercury vapor rectifiers in it was an old Raytheon AM transmitter. Needless to say, I didn't get to look at that rectfier in action. I'm curious as to whether this SHOULD have this beautiful blue glow. Once I put in new power filters the radio plays well and sounds great. Not a hint of hum.
This set also has the most interesting volume control I've ever seen. It's actually a part of the AGC circuit as opposed to being either in the antenna or audio circuits.
