Crosley 148
#1

I have a Crosley 148 I'm working on and one of the first problems I've encountered is the Vol pot has some bad spots so the resistance I'm reading is all over the place. Tried cleaning without success so I'm looking to replace it. None of the info I have shows what the Vol pot should be. Any Ideas??? Thanks

Hi Eric,

Crosley's are a little odd. I had the same type problem with a 124. If you don;t mind me asking, how did you clean the control?

Hi Eric,
You are looking for a pot around 10-20K It controls the cathode bias and the amount of the antenna that gets into the set.

Now I think I've got!

According to the schemat, the original pot is a 3 meg. Is the original in your set a wirewound type pot or carbon trace type? Does it look original or is it a replacement from original? If carbon trace type, RadioDaze has a 1 meg that should work. Their new pots have long aluminum 1/4" shafts, easy to cut to proper length and grind with a dremmel to make original knobs fit properly when replacement is absolutely necessary. As asked before, how did you clean your original pot?

I believe you're looking at the parts list for the 146:

This post states that the volume control should be 4600 ohm:

Thanks for all the replies. the pot looks original to me it has a brass shaft is 1.5" dia and 7/8" thick (big) and from off to full rotation is 3/4 turn of the shaft. I believe it has been repaired as the seam where it splits has been soldered in about 4 places and not very neatly. I decided to open it and it is a wire wound pot I cleaned it with qtips wet with alcohol and it seems to be operating better I measure 5k across 1 and 3 And the center (wiper) was all over the place but the more I cleaned ( gently) the better it has gotten will pick up a 5k pot as a backup

Hello, Eric: Many of the early Crosley sets had the wirewound volume Pots, and the common problem with them is the "wiper" wears through the wire, causing an open condition. Because the Crosley was an "affordable" set, they often have some wonderful problems that are directly related to their cheap construction. Additionally, early 30s Crosley models used cardboard filter electrolytics under the chassis, and they tend to leak electrolyte under the chassis and cause more problems.

This is not intended as a slam against Crosleys, as I myself like and own quite a few of the early 30s Crosley Cathedral models in my collection. In fact, I am listening to a model 127 as I write this. After the headaches that I had getting it to play, I am getting my money's worth out of it!
