Pioneer RT-909

Reel To Reel Tape Recorder (1979-1984)

Pioneer RT-909

Description

The Pioneer RT-909 3-motor deck, with auto reverse / repeat playback and many more features, takes the open-reel format another important and impressive step ahead of anything available in the cassette format.

You're going to sense this the moment you see it, and hear it, in action. Features? It's another loaded deck from Pioneer. It not only accepts the conventional 7 inch reels, but also the professional size 10.5 inch diameter reels.

It gives an exceptionally wide frequency range of 20Hz to 28kHz (± 3dB) and, to match this outstanding performance, gives low wow / flutter of 0.04% or better, with both specifications measured at the 7.5 ips tape speed.

It mixes microphone inputs and line inputs, another advanced professional feature. And it allows instant comparison between the tape and the original, as well as azimuth adjustments of the heads. Add up all of this Pioneer perfection and there's no doubt that the RT-909 is made for the person who has major musical ambitions and strongly professional tastes.

And yet if you've never considered making the big move upward into open-reel, because you thought they were too complicated, you'll be happy to learn that Pioneer has equipped the RT-909 with the kind of features that only an open-reel novice could appreciate. Things like exceptional headroom (and flexibility) that means this open-reel format offers more overall performance in terms of dynamic range, distortion and noise than the best of cassette formats. And much more: convenient automatic reverse / repeat playback, tape-saving 3.75 ips speed, easy to read Fluroscan meter and 4 digit counter, timer start, LED indicators, and other features.

Are you ready for the move to open-reel perfection? Pioneer has made a beautiful deck and equipped it in such a way that it performs with the ease and perfection of a cassette deck.

The low end bass response of the RT909 does beat out Akai's GX747 and Teac's X2000R both by quite a margin, considering your equalizer and speaker are rated to pick up lows that low, and did NOT have any distortion either at that low a frequency, so this unit has the lowest lows of all the reel units I've had here, the highs are GOOD too. I do not know why Pioneer didn't keep going on with their reel technology and add EE and DBX to their unit but it was selling SO well they didn't bother with that and kept selling up to 1984 like the rest of them did. These are wonderful units but the only real problem to look for would be the IC's in them which can cause the Fluroscan to have missing digits and not work at all, aside of that one problem I like the sound quality of this unit and mine is a keeper!

re: RT-909

pinch rollers, google Terry's Pioneer pinch rollers.....

RT909

I recently acquired a RT909 that is like new but has not been used for several years. One of the pinch rollers is very gummy, almost like it has been inked..is this normal or does it need replaced?

Gummy Pinch Rollers......

Whatever you do "DO NOT" play any tapes on the that Pioneer RT-909 reel to reel with the Pinch Rollers in that condition. That is not normal by any means.
Those Pinch Rollers definitely need to be replaced or restored.
To 'Replace', just do a Google search by typing in Pioneer RT-909 pinch roller and start hitting several sites and search. I'm sure you'll come across a couple of places that sell them.
To 'Restore', just do a Google search by typing in "Terrysrubberollers". This will lead you to his website. By sending them to him he will be able to have them restored.
Good Luck!

RT 909 SM

Would like to locate the SM for the RT 909. Need to replace the main drive belt.

belt change for rt-909

I recently purchased new pinch rollers for my rt-909 and it included a free belt. Installing the belt is a very tricky with small parts.

belt change rt 909 pioneer

anyone know what this involves without calling him to bother him? I am changing this belt soon....thanks!

re: belt change rt 909 pioneer

lay the player on a cushion face down so that when you remove the plate to get at the belt you don't lose the 2 tiny nylon bushes...

Pioneer RT 909 service bulletins

Hello,

Does anyone here have any of the rare service bulletins for the RT 909? I have only been able to find one of them online, and that after MUCH searching.

And to bradman16, replacing the belt involves removing the top and back covers. Then you remove the four screws holding the capstan motor mounting plate in place and slowly rotate it out of the way. Now there are two nylon balls, one each on the end of the flywheels. These can fall out when removing the motor, so be very careful and prepared to catch them if needed. Put a paper towel or masking tape under the motor before removing it. Once removed, pull off the old belt, clean the flywheels and capstan pulley with isopropyl alcohol, and slip the new belt onto the flywheels. It will hang loose. Replace the nylon balls if they have fallen out and add some lithium grease to hold them in place. Then rotate the capstan motor mount back around and bring the pulley of the motor down onto of the belt. Once everything is in place, screw the motor plate back in. You should be good to go after this.

Belt Routing

Hi,

any chance of a diagram of how the Belt should be routed?

Your explanation is superb but you just say ''.....slip the new belt on to the flywheels....'' Is it over one and under the other or is it literally around both? (Hard to explain.........hard to exactly understand what you mean)

Regards,

James.

Nylon Balls RT909

Always curious, What is function of nylon balls.

Planning to replace belt and pinch rollers. BTW who does a good job at re-capping the rollers?
Thank You, David

Nylon Ball Bearings on RT-909 Capstan Shafts

The purpose of the nylon balls is to limit the lateral travel of the capstan shafts in their bearing sleeve. The shafts are allowed a small amount of lateral travel but if the ball bearings are missing the shafts will move enough for the flywheels to interfere with each other. This situation seems to be worse when the capstan motor reverses. The flywheels will rub and bind with a lot of noise sometimes binding so bad the reverse play will stall.

The nylon bearings are not easy to find and metal ball bearings will suffice, but if you drop one of the metal ball bearings, you must locate it. It will always land in the worst possible place and do real damage to the electronics if not removed prior to power up. I don't have the diameter of the steel ball bearings, they are in the range of 2-3mm.

Alden

Thanks

Thank You, I appreciate your time in replying. Someone suggested Terry for re-capping, is he the go to guy?
Thanks Again,

David Woodruff
