SkywaveTDR:
Thanks for your reply.
Actually, since I posted this question, I’ve found the answer…well, at least one answer.
First, TEAC manufactured the A-2340SX, and like the A-2340/R, it does have sync. Apparently, it was a later model than the A2340/R. It differed from the earlier models in that the “Fast-Pause-Play” mechanical switch was eliminated and the transport controls were all solenoid controlled. I know for certain because I just bought one:
You might be correct that the same machine was sold under the Tascam name. However, if that’s true, it wasn’t the only one. Tascam also made the
Model 22-4L (3.75 ips/7.5 ips), a low-speed version of the Tascam 22-4 (7.5 ips/15 ips). Both versions of the 22-4 were made for up to 7” reels. The
Tascam Model 34 was made to accommodate up to 10” reels.
For the record, the reason I originally posted my question was because I needed to find a 4-track that accommodates 3.75 ips. (I have ~4,000 hours of 7” reels to digitize; all of which were recorded at 3.75 ips.) The TEAC A-2340SX I bought has been well-maintained, and it should perform well.
Nevertheless, I would have loved to find a Tascam Model 22-4L. Apart from the fact that it’s newer (and therefore is likely to have less wear), it appears to be a much more heavy-duty machine than the TEAC A-2340SX . I say “appears” because I have no direct experience with the 22-4L, but I suspect it’s an exceedingly well-made machine. I would buy one in a heartbeat if I found one.
Thanks again!
