Have you checked the schematics on this web site? I haven't looked, but I am sure they have all the Radiola schematics.
I think you have two problems with the present volume control. First and obvios is that is is worn out. Second is that you have the wrong taper on it. Usually voume controls need a logorithmic taper, although Radiolas may be different. The other kind of taper is linear.

Guys,
The schematic is on this site at:
http://www.nostalgiaair.org/PagesByModel/337/M0040337.pdf
Looks like the value is 450 ohms and where it is located is probably a wirewound.

Al,
Do you have a way to measure resistance? If you have an ohmmeter, measure between the two outside terminals of the Radiola 16 control. If it measures around 500 ohms then it may work.

A Radiola 16 controlled volume by adjusting filament voltage. The resistance will be very low, maybe 10 ohms. Too low for a Radiola 60 volume control.
Radiola 60 used a 450 ohm control. You should be able to find something close at PTOP, www.oldradioparts.com .

:::::Hi: I have a Radiola 60 that has a problem with its volumn control. Before my time someone replaced the wirewound with a pot. It is not working properly and cuts in and out. I've tried spraying it with good electrical cleaner and that works briefly but it goes back to it's old ways. Also the volumn is very low with minimal gain until half way through when it jumps to a very high volumn. What would be a good replacement pot for this model Radiola. I have an old but good one from a parts Radiola 16. Would that work on the 60? Thanks. Al

::I found the schematic although I'm not good at reading them. I understand it is a wirewound and 450 ohms. I'm new to radios so I'm not sure I know what a logorithmic taper is. Do you have suggestions on what might work as a replacement? Would AES have something and would the Radiola 16 wirewound work as a substitute? Thanks again. Al
