I think the Vol control is shot on my Crosley 148.
I see no parts reference data with values in the schematic I have been able to find. The Actual Crosley part number in the set is W26579B... Can anyone tell me what value of a replacement I should use?
Thanks, Bob

Can you measure resistance between the end terminals? If not, a resistance between 10K and 30K should be fine. I will measure mine and get back to you.

Thomas,
I have a digital ohm meter and when I measure the outside terminals I get erratic readings going up and down up and down all over the place. Makes no sense to
me.. I opened the back of the switch and there was a lot of wet brown grease-like stuff on the wire resistor area. I cleaned it off best I could but still could not get a stable reading. Sometimes I could get around a 150 ohm reading that did not vary too far but not consistently. I do not have any reference to find out
what size this pot is from a parts list..

Bob:

If you're getting erratic readings there may be a bad connection on one of the end terminals to the resistive component. If that's the case you may want to try taking a reading from the center terminal to either end, once with the control fully turned CCW and the other fully CW. One terminal should show no resistance and the other the value of the potentiometer. If the problem is just with a connection on one end, this should hopeully get you a good reading off of one or the other with respect to the center.

Incidentally here is a nice copy of the Crosley service bulletin for your set

Unfortunately the resistance value of the volume control isn't shown.

Thanks for the service bulletin! I could not find anything else besides the schematic. I looked at the control closely and I see a break in the very fine
wire on one end of the resistor path for lack of correct nomenclature. I think maybe that is at least
part of the problem. I am hoping Thomas gets back to me with the size of his control. He has a chassis like mine. Thanks for looking for that for me. I also gleaned some info from another post you put up recently...I think the audiophool site.. Thanks, Bob E.
