Pioneer RT909 Repairs at Local and Bad Shops

Recently I have been working on some decks here that have been badly butchered by local shops or so called Tecnicians that should really be called idiots because of what they do to these machines-

What has been observed are things like-

Broken off screws due to a drill being used to screw them in, stripped screws, Push on Pinch Roller rubber when they should be going to Terry for new rubber put on correctly. Cut wires all over the place, wrong belt sizes put on, power supply work that looked like a grade school person did it and I can go on and on. These people do more damage than good and then charge you for it.  One service guy said to the client that he could not repair the deck- what was wrong with the deck? A shorted Zener Diode. How hard can that be to detect? A first year Electronic college student would be able to find this.

If you have a nice deck like this be careful where you have it serviced as a typical $300 repair can easily get into the $800 range when we have to take off motor plate stand offs and install new ones and repair all kinds of other destruction caused by the service person.

To add to this- I have just spent some time on the phone with a client who has had his unit repaired and recapped by this guy on E bay for $750. Now as he sends the unit back for the 4th time it still is not working. The client tells me he has a 3 year warranty. Talking about sticking your neck out far, I though I was doing that with 6 month warranty. Regardless of stated warranties and this is the second 3 year warranty I have heard of, these shops need to be able to fix the unit right the first time not the 4th or 5th time. In both cases of these places having 3 year warranties, I have had their clients tell me they had to send it back 4 to 5 times and in the previous case after 5 times the client gave up. I don’t blame him. Do you? If you ask me if they can not fix a unit after two attempts that tells me they can not fix it in the first place. Just be warned.

Anyone advertising on E bay for work can not be very good and this is the second proof I have found besides that guy in NM.

Dual well cassette decks- WE do NOT work on them.

I continue to get calls that people want me to work on their dual well cassette decks. These usually sold for around $150. Doesn’t that tell you how they are made?

Suffice it to say that these decks of questionable quality in the first place run about $400 to repair as there are two separate transports to tear down and rebuild. Is is worth it? Certainly NOT!   They were considered throw away when they were made many years ago. The target audience was the 16 year old high school girl- does that tell you anything about the quality and their purpose?

If you have a broken one of any brand that is dual cassette, you are far better off getting an older solid made single deck like a Teac C-3RX or a Tascam 122 Mk II. Nakamichi BX300 is also another good product. You can’t buy a piece of junk and expect the Technician to make a piece of gold out of it- I have worked on them enough years that I know this is not going to happen.

Out of all the dual cassette decks made there was only one worthy one made and it was a Sony ES model that cost over $1000. That might be fixed.

Pioneer RT909 push on rubber Pinch Rollers

For those that are not informed and have no way to measure wow and flutter as well as phase shift with a scope, I am posting this so that you DO NOT waste your money on this garbage.

I finally tested a set here and had to wonder what was the problem with the freshly oiled and belted deck and it was the Pinch Rollers. These Pinch roller push ons are a bad attempt to make a product but if they did any testing they would find that they exhibit cyclic wow and flutter rising to .14% and that they are not very precise in that the azimuth sine wave shifts consistently at least 90 degrees each way. This is ridiculous that these are still being sold. I looked on Amazon and there are two 5 star rating reviews.

In putting on another pair of old rollers I had here the wow and flutter went down to .040% wrms and stayed there.

This is another rip off product to be sold to those that do not know better- my results have been confirmed by two other Technicians.

Also be aware that this same idea is being sold for Tascam cassette decks and the more expensive Open reels. No matter what the product is, the push on rubber is crap and you will NOT get good service from it. The only way to fix a Pinch Roller is to send it to Terry Witt in Sparta Michigan. This is what the professionals do. Don’t let these numbskull’s take advantage of you!
