Hi, I created an account after searching extensively and not being able to find any info specific to my situation.
I have a beautiful pair of Pioneer HPM-60's. I'm almost certain they're all original. They're rated for 60W/120W MAX and they have the cloth surrounds... maybe someone can chime in on the significance of this? From what I understand the HPM-60 were built with variances over the years and I've had some people tell me the 120W MAX they've never heard of, nor have they seen them built with cloth surrounds.
Anyways, as most of you probably know, these have the built in Mid/High controls on the rear of the speaker and they get scratchy and cause the mids and highs to cut out. At one point, the speaker failed to produce any sound at all and I had to "jump start" it by throwing full power/max volume and then it seemed to work fine. Anyone know what that's all about?
I finally got around to cleaning the pots to hopefully restore their functionality and now I'm at a loss. The High pot cleaned up well enough and looks fine. The Mid was oily and black. I popped off the backing to find it was covered in black, red and some rust. The ring that goes around the inside (fingers? tone ring?) is broken into 3 pieces and looks like something at some point got hot, melted and fused things together.
I need options.. can the pot be restored by a professional? I've tried searching for pot replacements with no luck... are there aftermarket pots that would have the same values as the originals? Could I just bypass the pots entirely without losing the crossover? I love these speakers and right now they're in alot of pain. Please help us.
I've included pics. Being powered by an Optonica SA-4141 65WPM and I promise this thing is like brand new and has no issues.
