Default WTB Crown ES-212 & PS Audio parts

Looking for a step-up transformer, 40:1, for a Crown ES-212 loudspeaker (lost one to lightening) and an emblem. Also a schematic for a PS Audio Moving Coil Amplifier (their terminology - not mine). Successor was called MCA-2.
Crown doesn't have parts for the speakers. Possibly a transformer from one of the other speakers in the line would work - not sure don't have schematics for other than the 212s.
PS Audio doesn't have any information on early units.

Default Crown ES212s and 224s

I also have Crown electrostatics, both 224s and 212s.
Please send me a PM with email address.
I may be selling off some of my Crown "stash" as we plan a move into smaller home.
If not looking to buy still contact me. I'm always interested in communicating with other Crown owners.
Thanks.

Default One more thing for analogalley

The former head of Crown service from Indiana was trying to get a manufacturer interested in making audio xformers for the 212 and 224 spkrs. Though he was not able, he has info (which I had sent him but I can no longer find it) of a place in Holland that can supply them.

IF you do PM me, I can give you his contact info.

I am unable to find how to send PM.
I then went to your profile and tried to send email (might be the way to do it). I found that you have disabled emailing. So.......enable it and post that you have enabled it. I'll receive notification from diyaudio and will respond.

Sorry about that...I believe that is all about the rookie 'moderation thing'. I checked my profile, and I see no place where I have specified whether others can or can not e-mail me directly (odd, as on most forums that is a basic configuration which you set when signing up). Of course, I may just have overlooked it If anyone knows what the deal is let me know!

Other than that I guess I am a bit stuck right now as I don't like posting contact details directly on a forum. I shall wait until either I figure it out or I post enough messages that I pass out of my 'moderation'.

I understand about posting contact info. I'm also a reluctant. I emailed the webmaster for assistance in putting us together. I have not received a note back. Perhaps you would also contact webmaster and maybe cite our correspondence and ask for assistance. You can mention that both of us would be happy to get PM from each other for the obvious reason.

Default Crown ES 212 circuit wanted

Can anyone help me with techical info on the Crown ES 212 Electrostic speaker. Basically I have trouble in the protection circuit which is "clamping" any input signal. The have been some changes in the power supply due our operating voltage of 240vAC. I do have a very simple schematic and the volrtage dropping resistor R5=3.4Kohm, has been replaced by an 18Kohm, as a result the input voltage to the high voltage step-up transformer is too low. By by-passing the R5 resitor and gently bringing the input voltage I have managed to raise the panel voltage to around 680 Vdc, I wary of going further because I'm not sure what the correct HT voltage should be on the panels. Also use a Digital Multimeter OK for taking HT reading or does one need and electrostic voltmeter that dons't load the circuit anyhelp please. John from Australia
