An RCA 140
#9

The radio was using a 6a6 for an output in place of the type 53. It's basically a six volt type 53. Pinout is the same and everything. Sadly, the question to keep this radio six volt or not has been rendered moot. The input transformer or power transformer is shot and will need to be replaced. Since I will be getting the same transformer for mine and the repair guy who also has a chassis like mine, we will be going back to the 2 volt type. What is it about some models of radios and their eating transformers? This one was replaced in 1945, so one would have thought it would be good, but it is shot. And this type of RCA chassis does seem known for bad transformers. Icon_sad

No matter where you go, there you are.
