Thanks again for your help. I was able to get these working by replacing the low-profile transformer on one unit and a 0.5 ohm power resistor on the 2nd unit. Both panels came alive, but needed more power than my McIntosh MC275 or Adcom GFA5300 was able to provide them. They sounded good and...

$1500 or fair offer. Very nice pair of original CLS's for sale with working panels and reconditioned electronics. I had these checked out by Russ Knotts, who replaced one of the low-profile transformers. I replaced one of the power resistors and both the panels came alive. I'm powering with...

Sorry--I've been quiet on this forum as I think I've located the issue, purchased some new low-profile transformers from MCI ($25/ea.) and have been in contact with Russ Knotts in Cleveland for some assistance. I'm sending the equalizer electronic boxes to Russ for inspection and service as he...

For anyone following my original post and who may appreciate the steps in trouble shooting your CLS speakers without knowing too much about ELS speakers, here's where I've landed. I found a schematic online and there's a simple writing on the top that says "Approx 280 volts at X former pins 5...

What is a "switched mains plug"? The interface provided is a 3-prong 120V input, so I plugged them into a standard powerstrip using MIT Terminator2 power cables. Is there a special power supply that is required to these? Do you mean that you should never try to drive the panels from the amp...

Jeff, Thanks for your reply--seems like you are the only one who read my post and had some useful insight. I did vacuum the panels, but the problem increased the longer I had them plugged in. Now, I get about 10% out of 1 panel and nothing out of the other. Switching panels with the...

I'm planning on using a MC275 for these, but that amp is with Mike Samra for some work. I've got it hooked up to an Alesis RA500 that should have plenty of power--maybe not the most melodic, but good for a stand-in. All in combination with a Janis sub and an Interphase 1a crossover amp.

Just getting into Martin Logans and would love to stay. Happy to share listening in Indianapolis, IN.

I came across a pair of CLS's and wanted to jump into electrostatics with these beautiful speakers. They look perfect with not a blemish in the mylar or panels. I hooked them up and they just don't sing. I hear music, but little or no bass and it sounds like they are muffled and dull. I...
