I have a Victor R-32 radio from 1929 with weak volume, It is at a real low level but can be varied by the volume control.
I have no schematic, And was curious if anyone else has worked on one of these or can give me a clue as to what might be wrong.
Power supply voltage is around 275v and both 45's are new.

Is that the one with the big slide rule dial?

Sure is, It's a real cool looking radio. And from what I have heard, A nice sounding one too.

Here is a schematic thanks to efforts of Scott Harvey. Note how the volume control is connected to the antenna. Do you have a long wire for the antenna. A proper ground also helps.

I'll email you the schematic. It exceeds the file size limit.
