Picked this up at goodwill. It was sitting on the test table plugged in. I did not even test.
I just bought it. I took it home and initially could not find anything wrong with it.
I did notice one major issue. FM would quit working and you would have to switch from AM to FM to get it back. Then it would drop out again.
I tested all the tubes and found that the 17ew8, and 12be6 were week. The 35c5 was intermittent and probably the reason FM would drop out. replacing all fixed the problem. The only issue remaining is that the alarm function of the switch does not work. I will have to troubleshoot that later.
