re: RT-707

Hola a todos: Es la primera vez que entro en este foro y expongo lo siguiente: Acabo de adquirir recientemente un PIONEER RT-707, la duda que tengo es que es un modelo americano, o sea, 120V; 120W, 60Hz, y me gustaria adaptarlo a la corriente europea, 220/240V y 50Hz, en principio pensaba que con solo un transformador normal tenia solucionado el tema, pero e conocido recientemente que el transformado solo es para el voltaje, pero la frecuencia no la transforma y podria tener calentamiento en los motores. Entonces lo mejor seria cambiar su transformador asi como cualquier otro elemento que influya en esto. Agradeceria me indicasen donde podria adquirir el transformador europeo, para el montaje. Saludos y gracias anticipadas

re: RT-707

I'm new to this site, and the reason for joining was that I got an Rt-707 and the only issue is when it gets to the last track or so the speed starts to diminish as if the reel was too heavy, and yes once in a while the tape gets of the guide, i push stop and goes back to normal, and the reels are 7", any help greatly appreciated.

re: RT-707

Hi all

Am new to this site and know little about reel to reels. I had an RT-707 about 30 years ago and have no idea what happened to it. Anyhow I have just bought one off ebay. It doesn't have any reels. Will it accept all 7 and 5 reels or are they specific to Pioneer? Also I have no idea if it has any of the reel clamps, are they still available? Best wishes Dave

re: RT-707

First you should get the users and service manual from here.
It wiil accept any 7" or 5" reel. If you want the original 7" metal reel you can find it on the Bay. Pioneer PR-85

No Belts

The Pioneer RT-707 (as well as the RT-707) does not use belts. They use direct drive motors to spin the reels. The "only belt" used in these is the "counter belt" which is small and really is not hard to replace, just have to move alot of things just to get to it.
As for any of the other problems, well may I suggest that you first download the "Service Manual" then proceed from there. For parts, well just search the internet there are a number of places that sell "used parts" but I seriously doubt that you will find brand new parts, if so they would more than likely be NOS.

Left channel output not working

I have a 40 year old Pioneer RT 707. It's still working but has a few issues. I am going to refurbish it. Can anyone give a basic idea of how to fix the left channel output. Also like to know where you can get parts for these machines. Belts etc.

RT 707 problem

Hi
I have a Pioneer RT707 that all of a sudden has a problem with its rewind spindle not stopping when it is in Fast forward mode, and stop is engaged, resulting in the tape unwinding off the spindle. Is there some kind of brake adjustment for the rewind spindle?

Any help would be appreciated.
Thanks,
Steve

I owned an RT909 years ago, & traded it in to the store where I bought it,
after I discovered that the brake hubs were made of plastic.
It's not a matter of if, but when you'll have a brake problem.
You'll have to open it up, secure the screws on the hub, and you may not need to adjust the brakes.
Check both hubs for loose screws.
I went back to Akai, the mechanisms are more reliable.

Pioneer RT707

I've been after one of these for ages and got one on Sunday. There were no tapes, manuals or even leads, so this site was exactly what I needed and it solved a problem I was looking into in one reading.

Thanks very much, I'll be back!

Manual availability

Thank you. It wasn't easy finding this website using the usual search engines. The effort was worth it. Thanks again for the manuals. I will return here again to explore.

Bias and equalisation settings

As an advance question before my RT-707 arrives, does anyone have experience of using Quantegy 478 low print through mastering tapes?

I have several of these tapes and would like to know what are the preferred settings. Obviously I can try different settings, but if I could benefit from anyone's experience, this would be preferable.

Quantegy used to be Ampex, as I'm sure everyone knows, but the type 478 is not listed in the 707 manual.

Any thoughts most gratefully received.

Many thanks,

David.

Thanks for a wonderful service

I have just purchased my first RT-707, and am currently awaiting delivery. I am extremely grateful for the downloads which I am sure will prove very useful in the coming months and years, particularly as I am a professional electrical/electronic engineer.

I have been looking for such a machine for a long time to complement my Marantz audio equipment, and this, apart from the 909, seems to fit the bill perfectly - the 909 is a little too large physically for me to accommodate.

The 707 is very similar in appearance to the Marantz equipment and fits perfectly into the special teak cabinet I originally had made for my audio equipment. For those of you who might be interested, the Marantz items, all from the same 1978-1980 era as the RT-707, are as follows:-

2130 Tuner
CD94 CD Player
5030B Cassette Deck (2 off)
EQ140 Graphic Equaliser
1300DC Integrated Console Amplifier (300watts)
6270Q Turntable

So, once again, sincere thanks to Hi Fi Engine for providing such a fantastic and useful service.

With kindest regards to all

David.

RT-707 Counter Belt Replacement

First of all I am so glad for the downloads of the manuals. It's great! However, in looking at them, I did not really see a place where it gave step by step instructions on replacing the counter belt. Does anyone have these details and or any photos on how to do this. Thanks.

I still have the step by step instructions with illustrations from when i replaced mine. Will send to your email on request.

Rt-707 Belt replacement

Hello; I have just found this forum while looking for step by step instructions for belt replacement on the R T-707. I would appreciate the assistance.

Regards mills4135

RT-707 counter belt replacement

From what I can remember:
1) remove the face plate
2) remove the black shroud over the left drive platter (2 screws)
3) remove the center spring loaded pin from the left platter (flathead screw)
4) remove the left platter (3 screws?)
5) loosen up the two screws holding the tape counter so that you can pull it forward slightly
6) take out the old belt that goes into the pulley groove behind the tape counter, and the left drive platter
7) put in the new belt, you will need to fish hook it over the pulleys, watch out for the grease, and don't get them onto the belt
8) put everything back in reverse order

I may have left out a step or two, but this should get you started.

did you ever get a reply to this ? I have one with the same problem

strange problem with my tr-707

Hi everyone! I have a strange problem with my rt-707, and if anyone can help me I would be very thankful! I just got it and everything seems ok, but when I press play, playing from from left reel to right, the capstan works fine and makes the left reel spin but the right reel fails to spin and the tape just unwinds everywhere. This happens when reverse played also. Fast forward or backwards works fine so the reel engines cant be out. But when played the are simply still, no motion, I dont get it. I admit Im using a 5" reel left and 7" reel right (thats all I have right now) but that shouldnt cause a total malfunction right? just unproper running. If anyone knows how to help out it'd make me real happy!

RT-707

I have seen it where the seller took off the two external rubber idler wheels to clean, and put them back on the other posts. One is smooth (or worn smooth) and the other isn't. I almost walked away on pick-up until I figured it out, swapped them at his place, then was satisfied and took it home. Still great (and I can't believe 30 year old commercial tapes still last and play well)

I seem to remember there is a

I seem to remember there is a mechanical pause on this deck, perhaps when activated this is the results?

Strange Problem

Comentario en español

Bueno, ya que lo dice pues yo tambien voy a comentar en español.

Agradesco a HiFi engine por Prestar este servicio de manuales. Mucho tiempo los estuve buscando, ahora ya no me preocupare cuando tenga que hacer alguna reparacion.

Pioneer RT-707

Thank you so much for this information I have a Pioneer RT-707 and it needs some serious adjustment. Wthout your information manuals my unit would be dead and collecting dust. Now after doing the needed adjustments and repairs the unit is playing beautiful music again.

Thank you
JW

Awesome, just awesome!

I have an RT-701 and have had no luck finding documentation for it, but since the RT-707 is similar I am hoping this will be helpful to me. I have a working unit and operation is not a problem for me, but I would like to have some guidance on cleaning and maintenance, so this will help a bunch.

Pioneer RT-707

Thank you very much for letting me down load the service manual. I appreciate it very much. I have got the RT-707 for 33 years and still going strong.

They told me to "Get Reel," so I picked up a Pioneer rt-707 !

Thank you kindly for the manuals, they are much appreciated.

All the best to you.

Many thanks . . .

for the manuals -- a most generous service. I just picked up the rt-707 from the scrap yard and all seems to be in working condition; just needs a bit of a clean. It's a handsome looking deck.

Thanks a million!

I will be picking up an RT-707 from eBay in the near future, and these downloads will be invaluable! Thanks for your efforts.

rt-707 pioneer awesom

I had forgotten how awesome these machines sound like; I'd just gotten mine from eBay, thanks for the manuals.

Thanks for the manuals

I always wanted a RTR since I was in an explorer post at a radio station when I was 14, some *cough cough* years ago. I picked one up this weekend at an Audio Karma swap meet - the Pioneer RT-707. Not a bad place to start in my mind. Sold a DAT at the same meet - nice karma - digital for analog. Thanks for the manuals. I sure would hate to do something stupid after waiting so long for one of these - and the manuals will help prevent that.

Pioneer RT 707

Thank you very much HiFiengine. You all are providing a great and invaluable service. Much appreciated. Bought a 707 just a few days at a yard sale for $20. with 18 metal reels loaded with rock and R&B. Works great but I'm a Teac guy myself. Might need to be tweaked, and the download will help, I'm sure. Can you believe it? $20. There's still bargains out there. Best to you all and thanks again.

Thanks HiFiengine.com, You are a lifesaver. I bought a nice old Pioneer RT707 reel to reel. It's been so long (1972) since I've owned a reel to reel that I have forgotten how to thread the tape. Thanks again, Sincerely, Richard Albright
