I was checking if anyone knows where you can find information or a video on how to do preventive maintenance on a Pioneer 701-RT Reel to Reel? I bought a manual on eBay it only told how to clean the heads.

You must NOT have bought the Service Manual. Cleaning and lubing should be in there (MAYBE)

I'm doing all that right now on the Sony but the books don't really cover that very well. It's pretty involved and relies on the person doing the services to know what they are doing. Be careful, take pics, and Good Luck. Sometimes it's easier to send it to a specialist.

Great advice. Taking on one of these machines without some knowledge or at least a little background in electronics can cause more harm then good. I wish him luck but I also think it would be wise to contact a tech with solid experience before he begins.

I practiced on my FREE Sony and am preparing to do the service on my Tascam 42-NB (at least the cleaning and relubing part). I'll have to see how the deck performs to see if the calibration part is needed. Maybe a recap.... maybe....

Doing extensive work on decks of this age will be a big task to those that are not used to this kind of work. It take some time to go through the process to get experience on the job. There are no books videos or other instructions I have seen except for the one on one training I do at my shop. Some people Email me with many questions and in the end they do repair the problems they have and some guy calibrate the deck as well buying all the needed equipment. It can be done but I tell people that to buy all this stuff is not wise for one deck- it is cheaper to let a pro do it. IF you want to get into the business then buy and lets get started. I help people get their own business started. There is plenty of work for everyone.

I'm contemplating that right now. I have to do some more reading and tear down this 42NB.... Could be fun

The Tascam 42NB is too new a product to worry about recapping at this time. Maybe in another 15 years there will be occasion to find a common cap problem on them. It seems to me that people do the opposite of what is right. They never want to recap Vietnam era decks and then here comes a 42NB or BR20 and they want to recap those. Lets use logic and some level of predictability of the failure of these parts as too many are wasting time with unnecessary practices. I can not remember a failed cap in a modern Tascam product but have experienced many failed parts in units of questionable component selection. Those would be the poor caps used in Technics RS decks and those that used 10V caps in cassette deck and even the Z7000. I have had these parts short.
In most of the 42 deck I have worked on they needed very minor correction and most of the problems come from people that get under the splicing block to turn tensions with not the proper equipment and then of course the decayed rubber on Tachometer and Pinch Roller. Terry makes easy solutions to this and I always have him do the job. The other thing is they used plastic feet on these heavy decks that are really not up to the task.
Parts Express sells a rubber amplifier foot that even when kicked by accident the Tascam feet would break but the rubber ones stay put. The same rear feet are used on Otari decks as well. The Tascam 40 series decks as well as 50 and 60 are great machines to have and work on.

My deck had a missing splice block. I hope they didn't mess with the adjustments under IT. I just got the rebuilt roller back from Terry so I'm going out to clean and lube it this morning.
