Hey everyone, I need a *dual* section volume control (no switch) for a Victor R-32. Both sections are 5.8K but a 5K will work. Anyone have one or know where I can acquire one?

https://i.imgur.com/VPLfnAR.jpeg

The control in the pic fits the chassis, but it was replaced in the past and is a dual 50K, so the volume control goes from 0 - 100 in 2 degrees of rotation.

I emailed Mark Oppat at where I've gotten parts in the past but haven't heard back from him. If he's busy, I'll wait but looking to wrap this otherwise completed project up for a customer.

Any help greatly appreciated.

Thanks Peter, I saw that. The shaft is too short but I bookmarked it in case I run into a dead end. I can drill and pin an extension on it if I have to. If I don't hear from Mark Oppat, that will be my plan.

Mark is very busy this time of year, as he is a (good) landlord that does most of his own work. I expect you will hear over the weekend, but he does answer the phone: (734) 207-2346, Monday - Friday, 11 AM - 8 PM, EDT

My approach to a short shaft is to use a spring-clip and a bit of JB weld as it typically does not interfere with clearances. There are also kits available with various shaft lengths.

cheaper.

Thanks again Peter. Anything I do to extend the shaft has to allow enough clearance for the outer collar that the radio uses to locate the front escutcheon. A spring clip might interfere with the outer collar but I haven't tested it yet. The control I
need is a round shaft and the control I'm looking at is a 3/4, so I may just grind both sides of the 3/4 shaft to a slot and notch a piece of round stock, then epoxy or even pin across the notch.

I'll wait the weekend for Mark before going the fabrication route.

I couldn't wait for Mark at oldradioparts.net to get back to me as I had a customer anxious to get this done. If it was for me, I'd have waited. This is what I ended up with:

This is a dual 5K with a 1.5" shaft, so it will only require a little trimming down to fit. It's also new so I won't have to worry about a noisy control. I'll also have to fudge a couple of 470 ohm resistors in, but it should otherwise work fine.
Thanks for the advice.

Just warn your customer that it is a linear-taper pot, and so the volume onset may be faster than with the original - unless that was linear as well.

Considering the one installed was 40K (!) this one will be far less a binary control than what it had even if the factory original was audio taper.
