Tascam 38 with stuck capstan and pinch roller

Hi,

I have a Tascam 38 whose capstan and pinch roller don't spin when playing back the reel and was wondering if there are any basic troubleshooting tips people can suggest. I haven't done any repairs on my own and I don't know how easily this stuff can be repaired on the user end. If this is too much for someone who's had no experience with repairing recording gear, can anyone recommend a place in the Los Angeles/Hollywood area that'll get it done? I had already checked Tascam's support site to look at their listing of official Tascam service technicians. Thanks.

What you're describing typically points to a bad capstan drive belt.

I'd make sure first of all that the tape is loaded correctly and that the pinch roller move fully up to contact the capstan. Likewise, if you raise the right tension arm up about an inch the capstan should spin CCW.

The capstan belt is not a mega tough job, but it's a moderate teardown. The faceplate of the deck should be removed. Often times the top "bonnet" cover is removed, which includes the back and bottom covers too, for easy access, but that's not 100% hard and fast rule. Lets say, for the sake of argument, that you remove the front face plate by itself, which is tricky but doable. The minimum of stuff to remove would be the "head cover" and knob for "pitch". The Pitch knob is tricky to remove at first, but no big deal as it requires a small pair of needle nose pliers to remove the nut that holds it.

Once you have the 38 naked in the front, there are 4 more screws that hold the entire head plate on, including the heads themselves. Remove these 4 screws and swing the head plate/heads out of the way to access the capstan belt. From this vantage point, it's easy to replace. Reassemble in reverse order of disassembly.

I'd say it's a moderately tough job for anyone less experienced with tearing stuff down and rebuilding it.

To the best of my recollection, the belt used in the 38 is 14.5" total length flat rubber belt.

What part of Los Angeles are you in? TEAC/Tascam America Hdqtrs is down the 5 off the Slauson exit. They have the main service depot there. In Canoga Park there used to be an audio service on Sherman Way named "Adrian". I'm an old DIY'er up in Palmdale. I've not done any fixit jobs in a while, but I have a few under my belt.:eek:;)

Hey Guyz, wasn't there a good pictorial reference of a belt job on a 30 Series deck somewhere here on the forum???

Thanx and good luck!

/Edit/ I see, LA~Hollywood area. It's an even shot for you in distance to either Adrian or TEAC itself.
Hey, there must be at least one audio service place in Hollywood! "Media Capitol of the World!" Haha, we all know that's Burbank anyway, but you get it!/Edit/

wow, thanks for such an exhaustive response. So, at best, it can be a bad capstan belt. And I presume that upon following your instructions, I can at least confirm whether it is a bad belt or not before going further to either ask here with my new findings or going to a technician. Also, can a worst case scenario be constructed with the few details I provided?

since you're giving me the green light on Adrian, I'll have to check him out. Thanks.
