The rubber pinch roller tire will deteriorate on its own over time regardless of whether iso alcohol is applied to it or not. Just like the belt and other rubber bits inside the machine.
Great vid to look through as I'm about to try to get my 34B working after sitting for almost 20 yrs in a wardrobe. The belt and pinch roller are both almost dissolved so I've ordered new ones from Ebay. However, eager to estimate the state of the machine I tried your trick to see if the capstan motor works. Unfortunately it does not seem to do so. I just read through the comment below where @VinnyDistefano had the same problem. I'll try the same trick, disconnect the motor and apply voltage to it. Also, that white string by the left tape tension arm is broken on my machine just like on yours. Very curios on what way you took to fix it, I don't really know how to tackle it.
Great video and very well explained , now I need to ask about the Reel table with back bush or pulley that holds to the shaft ,try to replace was wobling and the back bush was frozen tap a little and broke to pieces , now there's a special tool to extract that or was just frozen?
I just powered it up. Lights come on things spin around. I should probably try to find some tape next and see what happens. I have no idea how theses things work though
Great instrional video. I'm restoring a 34B right now, Replacing the tension arm strings. I freed up the hubs that the sring went around. I noticed on your machine there's a small metal arm that the rod goes through and the string attaches to the top of the rod. Does the arm sit on top of the lip of the bracket or does it hang down and move up and down as the rod moves? Thanks

Great video. I’ve just bought a 34b and the right tension arm doesn’t drop back down, so when I rewind the tape The deck just continues rewinding until I move the arm back down. Any info would be appreciated thanks
Sorry for the late reply. This got lost in the mix for some reason. Hopefully the issue is resolved by now, but if not… does the arm move freely? Or is does it feel stuck?
Hello Goodnight. I have a Tascam 34b and I don't know how to remove the front cover. I already removed all the screws and removable parts. I still can't get it out. seems stuck. What could I still need to take out?
There is an odd nut that goes around the pitch control. It has two slots on either side that you need to remove using a pair of needle nose pliers. Home that makes sense. It took me a while to figure it out. You can see me putting it back on at about 15:30 in the video.
hi funny thing i have worked on alot of tascam 30 decks the rubber roller goe's bad over time like the belt time to time re soldering on the record button have to be re solder in alot of place's on the pass links
Tascam 38 needs a 1.5 mm hex wrench. I’d imagine it’s the same. And then you need a pair of needle nose pliers to remove the nut at the base of the pitch control shaft
My Tascam 34 capstan stopped rotating. I have the service manual with the schematics, but can't find the transistors in that circuit. Would you know where I can find a layout of the pcB 137? I've been all over the Internet and zero. Thanx.
@@TheTapeFarm I already replaced the belt. When I lift the tension arm so the photosensor is in play, the correct voltages are present on the IC circuit chip U519, but I cant find the transistors to get to the next step without completely removing the control board to locate them which "m trying to avoid or jump ahead to locate the capstan motor assembly board which I'm sure is buried in there.
@@VinnyDistefano gotcha. So the capstan motor is not spinning up. Have you tested the motor? Applied voltage to see if the motor spins up? The only reason I’m asking is because it’s pretty rare for the components on the board to fail. I mean it happens for sure, but when I hear the beating of hooves I think horses, not zebras. So I would check all moving parts first before digging into the electronics.
@@VinnyDistefano Or if you can find the relay that feeds the capstan motor. You can check for voltage there and manually engage the relay and see if the motor spins.
Yes but also to roll off if the belt gets too loose. Otherwise there would be fluctuations in the tape speed as the belt loosened up over time. This way, it just slides off when it needs to be replaced.
hi i know that tascam man on the net who parts out decks alot deck he gets hold of are in a bad way i just fixed 2 tascam 38 decks THEY CAN RUN AT 7 1/2 OTARI 8 TRACK can run at 3 3/4 ips there a button in side the deck 15 ips 7 1/2 one way push it over 7 1/2 3 3/4 ips i spy it on a mate deck i have tascam 38 running at 7 1.2 the EQ has to be right

Very good thank you Australia Mr Sang

Awesome video!
I’ve got one of these. I know it’s broken but I’ve not actually ever plugged it in. This may inspire me to have a look at it
If it’s broken... you can’t hurt it. Open her up and see how she ticks.

It only moves when the arm reaches the top of its range.It acts more or less as a brake for the tension arms.
Hi, thank you for the videos you make, I ask you if you could do a tutorial for the repair of the tascam 34 brakes. Thanks
I haven’t had a need to fix them… but if I do, I will make a video.
@@TheTapeFarm You are the best.
Very nice Video I have the Tascam 34b. How would I connect this machine straight to a receiver for play back and record
Super super video! Main respect master .

Alcohol does not desolve rubber. The fault is in the rubber process. Belts that goo up have never felt alcohol.
what kind of oil is that you are using around 19 min mark?
You forgot the teflon-washers on the guides😳
That was great Thanks

my 34 b records and plays with high sharp treble and very little bass. please advise

Why don't you put clovers to work in a clean way?
Where can I order elbow grease ? (not available on amazon) Thanks
Gloves, sorry.
What's the name of the motor?
Could I send in my Teac reel to reel machine to you for some repairs?
Hey man. I don’t work on other people’s stuff. To much liability to make it worth while. Plus parts are getting really hard to find.
sir , where i can find tyres for the pinch roller, from where i can buy them
lalit trikha found mine on eBay.
What size hex wrench do you need to remove a tascam 34 pitch control knob?
Tascam 38 needs a 1.5 mm hex wrench. I’d imagine it’s the same. And then you need a pair of needle nose pliers to remove the nut at the base of the pitch control shaft
Perhaps that was a work for a client )) No button caps cleaning, no fresh lube, no main bearing replacement (it’s loud)

Have you checked the belt? That is the most common reason the capstan would stop.

Everything is working but the motor is not working and motor is also new...can you please help ??
Make sure the motor is getting power. If not you may have a power supply issue. Start checking fuses.
Fuse is also good...only the small motor is not working even we used a new belt
interesting. i always thought that the reason the roller had a crown on it was so it was self centering.
