Hum Balance Switch for Bell 3030

[aabum]

Hi, the hum balance rotary switch on my amp needs to be replaced. The spec listed on the Photofact is 200 ohm's, and the switch is dual gang. I'm having no luck finding such a switch. I've looked at Digikey, Mouser, Antique Radio Supply, and have performed multiple web searches with no luck. I've found single gang 50 ohm and 100 ohm for guitar amps. Any insight as to where I can find a replacement switch? Thanks.

Make, model and hopefully a schematic may help you with a resolution to your problem

a hum balance pot that's dual gang? i'd like to see that amp and how that's implemented.

Picture?

The amp is a Bell 3030. First time posting pictures, so my apologies if what I tried doesn't work.

An externally hosted image should be here but it was not working when we last tested it.

I noticed my post was moved to what appears to be mostly guitar amps when I originally posted in the tube amp section. Not understanding why that happened.

I can move it to 'Tubes'. It was probably placed here on the basis of you mentioning guitar amps in the first post and you not providing model details. It does all read more like a guitar/pa amp than a HiFi amp in that post.

> single gang 50 ohm and 100 ohm for guitar amps

Use that. Value is not critical. You will have to adapt the mounting.

> the switch is dual gang

It is not a switch and it is not dual gang.

What you see in the pictures is a dual, "stereo", pot. Not shown in the schematic.
