Re: [ARSCLIST] Repairing (or purchasing) a Uher



As Mike points out, these machines are a nightmare to get parts for, not to mention the fact that they were never really very good to start with. Rather than investing more money in a machine with poor performance and a limited lifespan, I would suggest pursuing modification of a studio recorder. The Studer B-67, A-810, and Otari MTR-10/12 would all be good candidates for this purpose, and probably the Ampex ATR-100 as well. Any of these machines will treat the tape much more gently than the Uher ever will.

We have modified two of our machines to play at 1 7/8 IPS with good success. I'm not sure what the issues are with getting the capstan servo to run at 15/16 IPS, but it is probably relatively simple, as the speed is changed by a series of logic divider chips.

You might want to contact John French at JRF and see if he can provide some specific recommendations. Their phone is 973-579-5773.

The University of Chicago Language Laboratories and Archives has four old Uhers (4xxx models) (used by various faculty in the field). None of them works, but two of them seemed repairable. I sent them out at the end of last year and got them back a week or so ago. Apart from personal problems for the proprietor, there was a delay in getting parts from Germany--and then only one machine was actually "repaired". I put it that way because, when it came back, it still did not work properly. Does anyone have any suggestions as to where I can get this repaired? I need the 1 7/8 ips (and would like to have the 15/16 and 3 3/4 ips) for some of the tapes in the archive.

I had my Uher repaired several years ago by the only recognized shop in Southern California (hence, probably the only one west of the Mississippi). It took some time and was costly, but the worst part was that they told me: never again. Parts availability was the killer, but I gathered that too few techs knew how to deal with the rather cantankerous machine.

May I suggest checking on a replacement for 1 7/8 and giving up on
15/16? Tandbergs are not the most durable machines around, but their
weakness has been alignment, not repair, and many shops can handle that
or you can acquire the modest skills needed. Models from the 6 on were
quite good at 1 7/8 and very fine indeed at 3 3/4.
