I have a Dreyfuss Hudson that is a PS2 upgrade. Purchased on the forum and it's a great engine. But I've never been able to adjust the volume manually so it has always been way too loud. Turning the volume knob (below) adjusted the sound from really loud to only too loud but now it doesn't work at all.
Do these knobs ever fail? If so can I replace it with one of the smaller knobs from a dead RTR Loco sounds tender?
Thanks
