Most of the cost would be labor, which wouldn't be much different for small or large panels. The materials would be a bit more for a larger panel because the double-sided tape especially, is ridiculously expensive. ML would stock these tapes in bulk quantities and meter them out as needed so...

Geeze, I feel your pain. And I'm guessing that cost does not include shipping? Even if you find someone to rebuild a dead panel (Russ Knotts at Just Real Music does good work at a fair price), it can't be inexpensive with shipping added in. I'm communicating with someone now who just...

Bigger is better... especially when you have a Lightstar to drive it!

Lust can drive fickle behavior. Could this same issue (owner selling relatively new speakers) be happening with other high end speakers (not just ML's)? This possibility occurred to me after recalling that one of my audio buddies recently sold a relatively new pair of Legacy Whispers, only...

Glad to welcome you here Dotcom, I hadn't heard of ATC until your post so I had to look them up. I've always admired UK gear, especially Tannoy and Quad. I spent a lot of time studying Peter Walker's equations for modeling ESL's, but it's mostly beyond my poor math skills. I think ESLs have...

Welcome Dotcom, I haven't heard the Impressions so anxious to hear your take on them. Are these your first ESL speakers?

Good question.... I'm not aware of any temperature measurements, and I haven't attempted any. If there is erosion/damage occurring due to the corona, I'm thinking it would have to be by cooking away the coating or rendering it non-conductive by making or breaking chemical bonds within the...

I suspect but can't prove it, and ESL manufacturers might be reluctant to confirm it if it were true: We ponder whether humidity plays a part, but panels losing volume over time could be solely the result of the high voltage corona progressively eroding/damaging the diaphragm's conductive...

I'm reminded that the original Quad 57 used a nylon coating on its diaphragm, which is only conductive because it's hygroscopic (absorbs water), and so it could hold more charge and actually play louder in humid conditions. But nylon isn't used anymore, and current diaphragm coatings are less...

I can only think of a couple of possibilities... 1. DIVORCE 2. The guy's so loaded (10k = chump change) he can buy and sell gear on a whim.

Hi Zoran, Humidity may or may not contribute to deterioration of the diaphragm's conductive coating. ML says no-- but it's fair to question that, given ML's vested interest and the number of owners posting about their panels fading. The coating is vapor-deposited indium tin oxide, which is...

Hey welcome to the forum! I'm an old guy too (70 soon). I have some experience building ESL's so maybe I can provide some pointers when you're ready to restore those Monolith II's-- or at least offer immoral support :-)

I want to contribute but I may come to regret posting this thread. Silly me... I had imagined walking an owner through a panel rebuild, and then assisting with a rebuild guide to be posted by the owner. This would be easier for me, empower the owner, and save shipping the panels to me for...

I would prefer a hybrid panel for the proposed rebuild guide, because that's what most owners have. But if you want to rebuild those CLS panels someday, I'll walk you thru it (it would be easier than you think).

Wow.. someone should jump on that offer real quick. I already have more ESLs than amps to drive them with (3 pairs). When I changed over to wire stators I gave away three sets of perf-metal panels for the cost of shipping. UPS destroyed one pair and I ended up taking a loss on the shipping...

Yes, I purchased materials for my very first ESL build from Russ many years ago. He's a stand-up generous guy and a great resource for panel repairs.

I would do it of course, but I prefer empowering others. I think it would be better if the panel owner (hopefully mechanically inclined) does the actual panel rebuild, with me merely advising and documenting. This would demonstrate that you don't have to be an experienced ESL builder to...

If it turns out to be a bad panel, you would probably want to take advantage of Tmort's offer in the previous post. But if you are more adventurous and would like to collaborate on creating a panel rebuild guide, see my post here: Panel rebuild guide?

Hi all, Occasionally someone posts a thread about an older speaker with low volume and expired warranty, and they end up purchasing new panels ($$ ouch). Panels can be rebuilt if the stators aren't damaged, and with all the DIY'ers on this forum, I'm a little surprised that someone hasn't...
