von schweikert vr 4

I did not fixed it yet. Albert called me and advised to contact Madisound for similar potentiometer.

did you fix it?

Thanks to everybody.

i've lost all sound out of one of mine. happened to the other side too, but i sent that one in under warranty.

the fix would be to replace the Pot. I've had this happen on a guitar amp - the sweeper became dislodged from the shaft in my case (as Ckoffend suggests). Pots are cheap, and not hard to replace. I'd call Von Schweikert before doing anything though.

You problems here. I don't adjust it very often, though.

I had the VR4JR for a while, but never had a problem with the adjustment of the ambiance tweeter. Have you pulled the plate/assembly out to confirm that its still wired? have you lost control or all sound out of the tweeter?

finally, is it possible that the dial has lost its grip on the pole and while you are turning the dial, it is not turning the pole/shaft?
