25K Log (audio) Pot for Musicman amp

robinbowesrobinbowes Frets: 2922
in Making & Modding
I've recently done some work on a Musicman 112 RP-65 combo (mostly a recap) and only outstanding issue is that the Volume control goes from off to full volume between 0-4 and doesn't do much between 4-10.

This is the circuit fragment:



I strongly suspect a log pot would sort this out, but I'm struggling to find one.

The original is a CTS solid shaft, like this:



The only similar 25k Log solid shaft pots I can find are Bourns, and the only place I can find them is Mouser, but they have a £14.40 shipping charge for orders under £33.

Does anyone know of an alternative source?

Thanks,

R.

    I’ve probably got one as long as you don’t mind it being used/salvaged. I’ll have a look later.

    Not at all, that would be great. :smiley:

    OK, the good news is that I've got a 1978 CTS 25K Log solid shaft. The bad news is that the bushing/thread is shorter - 1/4" as opposed to what looks like 3/8" on yours. It's also not in great physical condition, the ground terminal has been soldered to the casing and it's a bit scruffy (but does work).

    However... given that they're both CTS of the same era, it's very likely to be possible to take apart both pots and replace the trackboard on yours with mine, so making yours into the correct Log pot :).

    If that sounds good, I'll send it!

    That sounds good to me - I'm sure I can make it work somehow.

    I'll DM you.
