electrostatic

Not sure if DIY repairs go here, but I did anyway. I recently bought these Mosaic speakers at a local Goodwill. They were scratched, dinged & molested by crayons. I didn't know anything about them, but a quick Google on the phone told me that they were probably worth taking a chance on. They...

Been running a pair of philco electrostatic panels (the semi-cylinders, from the 1959 consoles) as tweeters in a triamped system. Was sort of an elaborate experiment, conducted with aesthetics in mind as much as anything else, and it was working well until yesterday…I was making a stand for one...

Have you all heard any of those "chi-fi" planar in ear monitors on amazon? I ask about planar ones as a fan of the electrostatic sound. Seems like few buyers of these amazon IEM's come from big stereo setups -- not that there's anything wrong with that :beatnik: I got myself some Letshuoer...

Hi, I’ve been offered a pair of KLH Model 9 Electrostatics for $1000! Told they are in working condition, and can be demonstrated, but I know very little about electrostatics and I’m curious if this is a good buy/price? Also looking for info on what I should look out for when inspecting them...

Time passed ... Acoustannoy lost his email boxes, adress changes ... But still there ! I continued tweaking, reparing refurbishing my loved Electrostats, starting with Acoustats 1+1; then 2+2, then Spectras 1100 & 4400.... By luck I could find 2 pairs of Michael Wright's -another genius-...

Hi everyone. I’m a frequent reader but not much of a poster. But I have run into something and wondering if anyone has seen this before. I picked up a pair of RTR ESR-6 speakers today. They seem to work but the output is low. I have read in forums here about the .01 3kv cap may be bad or the...

SOLD! I am very excited to be offering a very unique speaker for sale at the HHA showroom. I have a pair of Quad 988 electrostatic speakers available. These speakers have been fully restored by Sheldon Stokes at SDS Audio Labs in Grantham, NH. Sheldon is the de facto ESL expert in the US and...

I just acquired four 45.5”x8” electrostatic panels that I am looking to test. I know that I can’t test them like a conventional speaker, but I am not sure how else to do it. There are three identical wires coming out of each panel. Also, since I could not find a brand, model number, or any other...

Hello, I have a new power supply board coming that I bought off eBay, I’m a little worried because the current one I have has four wires at the top right and the one I ordered only has two. I’m not sure what to do.

I bought my wonderful speakers in 1982. About 20 years ago, I had to replace one of the electrostatic transducer panels, and that went well. Recently I've had more problems that have turned very frustrating. Last autumn, one of my speakers had audio output way down. I quickly discovered that...

Hello - I'm a longtime reader, but this is my very first post... please bare with me as I'm a beginner. I just picked up a pair of what I believe to be Bozak B-302a's that have been modified - the original mid driver and tweeters had been removed, and replaced with a JansZen 65 in each of the...

Just picked these up today. Unfortunately they came untested, so I was a bit stressed out by the time I was hooking them up. Fortunately one fired right up and sounds wonderful (my first experience with electrostatics). The other makes no sound when attached and plugged in. Wondering where I...

Need some advice - - I'll probably have to check with MartinLogan too but I thought I'd start here! Own a pair of Sequel II electrostatic speakers. One panel has become very directional, and it seems as though only the right half of the panel is producing sound. This is confusing the living...

Hi: I recently acquired a pair of early 60s Janszen Z-600s. After repairing one of the speaker's electrostatic tweeter's connections, they sound great on the high end, but seem a bit lacking on the bass, which I understand is common with early electrostatics. Is there an easy way to address...

Not sure if this belongs here or in DIY.... I'm working on crossovers for Realistic Electrostat 2s and need to replace the resistors (speakers, not power supply). I'm having a hard time finding exact replacements in my stash. I'm trying to do this with what I have vs. ordering — the shipping...

Hello. I'm attempting my first cap replacement and purchased some Orange Drop caps. When I went to install, found there are no polarity markings. Come to find out that Orange Drops are not polarized. First, is it okay to use them as a replacement for electrolytic caps? Second, I'm assuming...

What would the value be for a mint pair of KLH Model Nines that were owned by one of the engineers of the Model Nines design team?

I picked up a STAX SRD-34 Electret system on eBay. So far I've tried hooking it into a 20 watt Scott Stereomaster, a 38 watt Marantz, and an 80 watt Onkyo TX-906. I had the best results with the Onkyo, but even there couldn't get it above a medium low volume before I started hearing clipping...

Recently I read a review in a high-end magazine, of some Harbeth speakers, where the reviewer compared them glowingly to his Quads: "...a comparison not to be chosen lightly as it has the same neutrality, naturalness, musical authority, midrange beauty, and a really extraordinary top-to-bottom...

I'm not sure which forum is best for this question. Thought I'd give the DIY group a shot. I came across three Janszen electrostatic panels and would like to test to see if they are in working order. Does anyone know how best to test these? Should good panels rear a certain resistance? Thanks-

A few years back, I got ahold of a set of Martin Logan Sequel IIs that were in need of repair--the price was so dirt cheap that I couldn't resist. They were in Connecticut, and I wasn't, so a friend kept them in storage until I was able to pick them up. I finally got them last year in August...

The day is finally here. Since getting them in mid-April, I have been steadily working on getting them going again. Having worked on the Model 5's prior, I was much more comfortable tearing them down and working through each area until finally, tonight, I put them in place for some listening...
