I have had a couple Teac A2340R since 1974 & they are basically bullet proof. The heads hold up great. My tapes I recorded on them back in the 70's still sound great.



re: A-2340R

hi folks,

here's a question for the community here.

is it possible to change the heads on this machine for the heads from a 3340 simul-sync machine?

i have my eye on some heads from the simul sync version of this machine, the bigger sibling machine with the synch heads.

i'm wondering if its a case of a simple swap, or if there might be more involved.

has anyone done this?

i'd like to multi track on this machine if possible.



re: A-2340R

One of my meters is not functioning. No light. Can someone suggest where parts can be obtained for this recorder?
Thank you.

re: A-2340R

I've seen them on ebay. I've bought complete unit's at garage sale for $20.00.

re: A-2340R Autoreverse problem

Hey, all. Question: I added metal strips for autoreverse to some new tapes I bought. The material is made specifically for this purpose. I used 1.5" strips. First one worked fine, the next two not at all, and when I went back to the first one (that was working fine), it didn't work. Where is the sensor? Do I need to clean it? Adjust it? I can't find a reference for it online. Any ideas.

Thanks in advance

re: A-2340R Autoreverse problem


The "sensor" is two metal posts that are in the tape path. The metal foil bridges the contacts that activate the reverse mode. The metal tape needs to be long enough to contact both posts at the same time. The service manual doesn't show them specifically, but it looks like they are on either side of the playback head. If you look at figure 4-4 in the service manual you can see the two posts that are below the head block assembly and protrude through two openings.

A general rule of thumb is to keep anything that comes into contact with the tape clean.

It looks like the sensing strips activate a relay that activates the auto-reverse mode. It is possible that the relay contacts need to be cleaned due to the age of the unit. Do you hear a click when the foil is near the head mechanism? If so, the recorder is sensing the foil.

Also the auto reverse may only function in 2 channel play mode. There would be no reason to play a 4 channel tape in reverse.

Hope this helps,


re: A-2340R

I am new to this, but I also have an issue with auto-reverse on the A2340R. It doesn't work. The unit will playback in reverse direction, but only after I adjust the left guide arm so the the tape is on the opposite side than during normal operation. Manual doesn't have any info regarding reverse play. Any suggestions to troubleshoot and correct would be appreciated.

My problem; need metal strips to attach to tape. Other than operator error it works fine.

re: A-2340R

I think you may have it threaded wrong.
The tape should go under the far left arm and over the second guide.
If you got to eBay you can probably see the correct way to thread the tape.
Also, yes, you need foil on the back ( shiny ) side of the tape, not the media side.

re: A-2340R

I have a a-2340r and it works great so far but I wonder if it only records in one direction...it will do reverse but cant get it to record 2channel in reverse like most recorders do.

re: A-2340R

Most reversing decks do NOT record in reverse unless specified.
That is a forward recording deck ONLY>


re: A-2340R

Ok and thanks....at first I was thinking maybe it needed repair but recording in one direction for a 4 channel deck makes sense.
I have a Sony tc-730 that's records in both directions is why I needed to ask.....Teac is a new one for me...plus I have a 2340 that will go to a shop soon....
Thanks again.
