For the A battery I'd use 2 D cells in parallel.

Before you apply power you may want to do a basic replacement of capacitors, especially any electrolytic capacitors, the AVC filter, and the audio grid coupling capacitors.

The reason these radios sound worse than normal radios, is the audio output stage is necessarily very low powered, so the speaker is designed for efficiency rather than sound quality. They can be okay though. I like yours because of the fancy grill design and late 30s deco cabinet.

How do you parallel "D" batteries? is it positive to positive or negative to negative?
