Electrostatic speakers

Just an update. I was able to fix the speakers. I found a guy online named Russ while looking for a company that might do the repair. Great guy . He was a dealer and an authorized repairer of quads, Martin's, and sound lab. He is retired now but we hit I off talking about our love for speakers. He gave me a sample test to do for the panel I thought was dead. I did end up pulling them apart to replace the copper strip that connnets to the membrane. They sound pretty good given the room they are in the warehouse of my job. Just have to figure out where they will go in my house now. Thanks for everyone help.

I paid $600 for the pair sight unseen. I’ll look around for some pricing. I may just cut my losses. I was going to build a pair for fun. Maybe I’ll use these as a starting point. Thanks for the help.

Not sure how much you have "invested" in the panels but you could be in for a very expensive repair. Today’s electrostatic designs are much better and very reliable. Older designs...not so much.

It looks like it is the panel. i tried to vacuum them. no difference. i did switch out the panels with the bases/woofers and the problem moved with the panel. Can anyone recommend a company who rebuilds panels?

Use a brush attachment and make shure it’s clean. But first disconnect the speakers for 5-6hrs, preferably overnight 

There are no places to adjust anything externally 
Thanks I’ll give the vac  a try. 

Vacuum the panels. Dust accumulation on the panels can do that. If it won’t help, the panel is most worn out. 

Here's a pro review...

The only information i could find on them was a review from Vault.

i did try to switch the channels. it made no difference. I've checked the fuses also. funny thing. i did not think the woofer were powered, but the on/off switch dose not seem to make a difference in sound on ether speaker. i was going to try swooping the panel next. When you say they degrade is it the coating on the firm/membrane? i wouldn't think the transformer in these would degrade.

thanks

I couldn’t find any information on these from an, admittedly short, Google search. 
 

Do they have bias adjustment? Check the back of the speaker for some sort of pot that is adjustable.

Not unusual as electrostats age and one panel degrades more than the other.  

Did you try the obvious and switch channels to make sure it's not the receiver?
