Joao Silva2011-04-04 21:34

I have a pair. Working fine. Never heard better sound

Curtis Fry2011-04-12 23:03

I own a pair of these. Very satisfied.

Joao Silva2011-04-13 00:00

also, I have all the schematics, once RTR sent me

Curtis Fry2011-04-13 01:45

I'd like to get a copy of the schematics. How can we work this out? My email:

<freemone233@comcast.net>

Thanks. Curtis

Joao Silva2011-04-13 02:34

Will find a way. they are large blue prints. will have to split to A4 format. will be back with a solution.
Did you ever had problems with Cinch-Jones connector?

Curtis Fry2011-04-13 23:44

Thank you very much for offering these plans to me. As far as the connector, once I got these home and reconnected, a yellow warning light came on one the ES. I contacted the seller and he said DON"T PLAY THEM since the warning light could be a sign of weird oscillation. I switched the ES from one woofer set to the other and the warning light no longer lit. Sometimes, getting those halves together is a pain due the way the connector is located right in the middle of the unit. Fortunately, the "play" in the male end from the ES helps if my aim is somewhat awry. I was warned about those connectors - be careful NOT to crush the male end. So far, so good.

John Smith2012-02-16 01:28

Hello Joao Silva,

I also have a pair of rtr dr1 speakers but have a problem on of the speakers. The bass speakers works on channels but no sound or light from the electrostatic speaker on one side. I need to take them in for repair. I would be interested in a set of schematics as well. Please e-mail me and maybe we can work something out. Thanks in advance.

I own a pair of RTR DR 1 Dymastatic and at the moment they work fine but I would interested to get the tweeters panels ELS as a spare parts. Where I can find them?

Alternatively, do you suggest other company which makes this kind of ELS panel (I think it's called HF 50)?

Thanks in advance

Alberto

Curtis Fry2012-04-03 23:27

Alberto,

The DR-1 does not contain HF-50 panels but a unique circumradial design exclusive to this speaker. Unless you find a pair for sale, as in those currently on eBay for $1,000, I doubt you'll find replacement ES "tops" for these. Good luck!

Curtis

Alberto2012-04-04 07:23

Thanks Curtis for your reply.

I bought a pair of RTR DR 1 and I would like to check if the ES tops work properly. At the moment they seem play ok. Do you have measeuraments and schematics for this kind of job?
And in case the ES top, after check, they are low than the original data where I can rapair or refurbish them?

Thanks in advance

John Jay2012-05-14 14:33

I also have a pair of DR-1s. One of the electrostatic amps is not working and would like to get the schematic so I can get it repaired. These are some of the finest sounding speakers. I also have two of the RTR subs. It is still an awsome system.
Please contact me with whatever info you have.
Thanks...

James Weigand2012-05-28 21:58

I have all replacement parts for the DR-1.....We purchased all the inventory from the original RTR last year. Have complete amps and top heads too.

John Jay2012-05-29 00:04

James,
Do you have any info on getting the electrostatic amp repaired?
How much are you selling the amp for? My email is jjroxguard-breezin@yahoo.com.
Thank You.
John

James Weigand2012-05-29 00:15

No I just have new amps, I would sell one for 675 + core (225.) I know there were transformer issues with the early models, let me know, James

William2012-12-27 15:58

I'm looking for a copy schematic diagram for RTR DR 1 Dymistatic, who can help me to find them?

Jim2013-01-17 16:15

I will look for it, I am sure I have them it's just finding them that's the trick.....I assume for amplifier?

William2013-01-19 15:51

Yes, I'm looking for a copy schematic diagram for the amplifier RTR DR 1 Dymistatic.

Joao Silva2013-07-08 17:10

Do you have the original speaker units? How can I contact you?

Yes I do, bigjimmiey@gmail.com

Scott Campbell 2014-10-21 22:09

Hello,

I'm located in Sydney Australia and own a pair of the RTR DR1.

Unfortunately, the audio transformers in the amplifiers are open circuit.

The all important circular panels work perfectly though !

Would anyone have spares or replacement transformers ?

Regards

Scott

Jim2014-10-21 22:13

I have complete amplifiers but no transformers themselves, sorry, jim

Scott Campbell2015-06-25 07:36

Well, I have my DR-1's up and running at long last.

They sound very good indeed. However, now that the panels are working correctly, I've found all the bass drivers have been replaced by cheap Dai-ichi drivers.

Can anyone tell me what the correct drivers are for this model please ?

Dean Janson2016-10-30 01:52

Hello,I have a great pair of rtr dr-1. They work perfectly. Can anybody tell me where I can get a dr-1 manual? Can somebody e-mail me the connection specks and or the overall specs,oops,miss spell. Send them to jansondean@yahoo.com. Tyvm,Dean.

Dean Janson2016-10-30 02:36

Hello,I am trying to locate a RTR DR-1 manual for my dr180's. Any connection type information would help,I had the original white book that came with these but something happened to it and I never saw it again.If someone has one of the white RTR DR1 speaker manual/book's I would like to purchase one. Thank you very much,Dean.

Scott Campbell2016-10-30 06:22

Hello Dean,

I tried to email you but says the email address is unknown ?

Saw your post about the DR-1. I have the original user manual for the DR-1, but it doesn't show any internal wiring hookups?

All it shows is the connection of the driver amplifier for the bass drivers, and the inputs for the tweeter amplifier ?

Regards

Scott

Timber Dawn2016-10-30 21:48

Hi Scott, I am writing you on behalf of Dean Janson, I'm a little more tech savvy so I have been trying to help him find this manual online. Would you mind sending that Manual pdf to my email at TimberDawnChild@gmail.com so I could get that printed out for him. Thank you for your time, we hope to hear back from you soon.

Timber Dawn2016-10-30 21:53

I just reread your post and noticed you said original Manual, are you willing to sell that or are you wanting to photocopy it? Hope to hear from you soon.

Scott2016-11-01 12:03

Replied to your email address yesterday.

Regards Scott

John Jay2016-11-01 13:38

I have a owners manual and have quite a lot of years of experience as an owner of the DR-1 speakers and the various setup arrangements, ie...with electronic crossovers and the RTR subwoofer, etc. I would be happy to answer questions.
One of my Dr-1 amplifiers stopped working and needs repair. Does anyone know of a an available schematic for the amp or a tech that has experience in troubleshooting and repairing the DR=1 amplifier?
John

Jim Weigand2016-11-01 14:15

I have it all, manual, schematics, literature, original drawings and parts. I am away on an equipment buying tour and will be home on the 15th so if you'd like to get ahold of me then I will be happy to help you out, Jim.

John Smith2016-11-01 23:36

Hello Jim Weigand,

I really need a copy of the schematics. Please contact me. Thank you.

Scott2016-11-01 23:39

Dear Jim,

I'd greatly appreciate a copy also. Id also like to offer to reimburse you for any time & money spent ?

Regards

Scott

Dean Janson2016-11-02 05:07

Hello,ok I will let you know if I have any luck finding the white RTR DR-1 speaker user manual. So far no luck at all as it is a very sought after pair of speakers therefore the manual is very difficult if not impossible to find. Dean

Dean Janson2016-11-02 05:51

Hi Jim ,sounds like we all really need your help with user manual information,hope you had a great trip. Dean.

Dean Janson2016-11-02 05:56

I'm trying to find someone who will sell me a copy of the white DR-1 user manual. Please let me know if you have one you would consider selling,thank you. Dean.

Scott Campbell2016-11-02 06:42

I have the fold out brochure type user manual, if that's any use ?

Happy to scan and email if needed.

Scott

Dean Janson2016-11-03 05:02

Hello and thank you Scott,that would be great if you could send me what you have. I have only ever seen the white RTR DR-1 speaker user manual. Thank's again.

Timber Dawn2016-11-09 02:32

I found a site that had the manual. Here is a link to the page if anyone else needs or wants a copy.

IF YOU HAVE ANY PHOTOS OR LIT I WOULD LOVE TO SEE THEM!! RMATLANTIS@COX.NET. MY FATHER RECENTLY PASSED AWAY AND ONE OF MY HAPPIEST MEMORIES WAS AUDITIONING THESE SPEAKERS.. :( DID THEY ALSO HAVE A SUBWOOFER AS A THIRD CABINET? MY MEMORY IS 40 YEARS OLD..

Dean Janson2016-11-21 23:45

Sorry no photos or tit.

John Jay2016-11-29 22:31

Hello,
I wanted to let those interested in the white DR1 Speaker System by Dymistatic Owners Manual know that I now have a PDF of it that I can email to you. I also am working on getting the RTR PS/1 Pyramid Satellite & DAC1 Rhombus Subwoofer manual in PDF form.

I would also like to make contact with Jim Weigand about getting a copy of the DR1 amplifier schematic if that is available. Jim if you could contact me at the address below it would be greatly appreciated.

Hello all. I have a pair of the RTR-DR1 speakers. I just had all 6 bass speakers reconed. They work better than ever. The wood cabinets are very beautiful. I will entertain offers if anybody is interested in purchasing them. Keep in mind these were $6,000 a pair new and worth every penny. These are hands down the BEST speakers I have EVER heard in my life.jansondean@yahoo.com

Rich Moore2016-11-30 16:04

I HAVE BEEN OFFERED A SET OF RE-CONED AND CAPPED UNITS IN THE SEATTLE WASH AREA FOR 2K. WHAT ARE YOU ASKING? RICH 805.272.0677

Dean Janson2016-12-03 04:53

2K each I would hope. I haven't at the moment a set price.

Dean Janson2016-12-03 04:54

These were $6,000 a pair new.

Jim Weigand2016-12-03 16:29

Suggested List for the DR-1 in 1981 was 1800 each

John Smith2016-12-03 20:18

Hello Jim,

I am looking for schematics for the DR1, especially the amp schematic. If you have these available, I may be interested in purchasing them. Please contact me at cm123451@gmail.com

Thank you

Dean Janson2016-12-04 00:05

Hello,I got mine from somebody on this forum.my dr1's or also called the DR180 are for sale.

Dean Janson2016-12-04 00:09

When these full sized dr1's first came out the magnolia hi fi location in Lynwood Wa sold them for $2,995.00 each. I have seen the original reciept from my original speakers purchase. That was the price.

Dean Janson2016-12-04 00:39

John jay can you please send me the PDFs you referred to in your post please"jansondean@yahoo.com

Jim Weigand2016-12-04 00:44

I have the original RTR price sheet with dealer cost and 1800 is what it says.

Dean Janson2016-12-04 00:46

Wow that's cool. Aren't they awesome sounding!ððð

Jim Weigand2016-12-04 00:48

Yes, very. I have a new pair in box. 6 used ones.

Scott2016-12-04 01:03

These are obviously a rare and desirable model. Not surprisingly when you consider the skill that went into the electrostatics arrays!

Mine are missing the correct 10" and 12" bass drivers. Does anyone have a suggestion for replacements, or information on the original drivers ? I've completely restored the cabinets, overhauled the amplifiers (with thanks to Jim for invaluable advice!) and I'd love to get them back to completely original specs.

Regards from Australia

Scott

Jim Weigand2016-12-04 01:07

I can find the 10's they are an alnico with foam, the 12" is the same woofer as they used in the Fulton Model J except they used a foam surround instead of accordion.

John Jay2016-12-04 01:59

Hello Jim Weigand,
Do you have a copy of the DR1 electrostatic amp schematic I could purchase from you?
Please contact me at johnjay.studio@yahoo.com
Thanks,
John

Scott2016-12-04 02:02

Thank you Jim, that's good information to have. I'll get looking for them, unless you have any spares you would part with ?

Regards

Scott

Jim Weigand2016-12-04 05:30

Scott, if you are not in a big hurry I can muster the 6 woofers together for you. Will take a little time though, Jim

Scott2016-12-04 05:43

I don't know what to say Jim, other than thank you very very much!

After 5 years ownership I'm in no great hurry.

I'm in Australia but more than happy to pay costs.

Please let me know if there's anything in the audio department that you're looking for, as I have many contacts and would be happy to return the favour?

My email is audio@tradeontheweb.net

Regards

Scott

Jim Weigand2016-12-04 06:07

No problem Scott, glad to help. As for John Jay I do have schematic of the amp but it's on another computer so will take me until next week to locate it. I had it digitized from a boiler plate drawing so should be pretty good contrast.

Rich Moore2016-12-04 14:37

A COPY OF THE SCHEMATICS FOR THE RTR DR-1'S WOULD BE OF GREAT HELP. RICH MOORE RMATLANTIS@COX.NET

John Jay2016-12-04 15:50

Jim,
That's great news! Like Scott I have been waiting quite a few years since I have heard them. I look fwd to having the schematic so I can finally start checking out what's wrong with the amp.
Thanks,
John Jay

John Smith2017-04-03 03:52

I have a pair of 10 inch and a single 12 inch ORIGINAL speakers for a RTR DR1's for sale. All need to be reconed and rebuilt if anyone is interested.

Jim Weigand2017-04-03 04:34

I am what are you asking and where are they located?

Rich Moore2017-04-06 22:21

John Jay, you mentioned you also have a pair of RTR subs? Are these of the same era?? Were they designed to pair with the dr-1's? do have any pics? Powered subs? thanks a million. rich

Jim Weigand2017-04-06 23:10

Ahh, are you selling the stuff you said?

Scott Campbell2017-04-06 23:30

Rich More

I have a pair of the RTR Rhombus subs that I believe were paired with the smaller speakers in the DAC system (?)

Do you need pictures of any specific part of the subs ?

Regards

Scott

Jim Weigand2017-04-07 02:35

why would i need picc?

Scott Campbell2017-04-07 02:42

No problems Rich,
