See a later post for Parker's enlightening answer as well as a very nice
testimonial to Studer and the A820.

Mark has indeed been kind enough to encourage me to put an A80RC here to
good use. ( http://www.sonicraft.com/a2dx.html#2T -- scroll down a bit

Not everyone has the budget to properly repair tapes with sticky
splices. Especially, when there are upwards of (70) 15 ips 10.5" reels
literally *riddled* with them. We had such a job come in and we ended up
evaluating a few machines to decide which to use.

We tried this job on an APR-5000 first. As expected, this machine got
very high marks for its gentleness. The jog shuttle allowed us to FF and
RW at a low speed, which is a big plus with challenged tapes. It also
sounds very nice. However, splices snagging on static surfaces in the
tape path were audible. 

The Technics RS1500 (same model that Tom Fine likes) is really a
terrific little machine for anyone on a budget. It did the absolute best
job of playing the tapes without dropouts from the splices. This, we
felt, was an advantage of its IsoLoop tape path. We could see the supply
reel bounce as sticky splices let go of the layer of tape underneath.
Yet never did we *hear* the bounce in the transfer. And, its constant
tension FF & RW was gentle enough that we felt relatively (although not
completely) comfortable. We didn't feel that it sounded outstanding, but
certainly very respectable. 

The Studer A80RC is very gentle on tape, although perhaps not quite as
gentle as the APR-5000. We were pleasantly surprised at how well it
handled the sticky splices -- almost as well as the Technics. It has
adjustable FF/RW speed and we felt very secure slowly shuttling tapes
whenever necessary. And, this particular model of A80, with it's second
generation class A discrete transistor playback amps, sounds very nice.

Using the Studer meant that we'd have to eat the cost of fixing the
occasional splice-related glitch that made it past the machine's
transport. But, great sound wins out here and we decided to use the
Studer instead of the Technics for this particular job.

Hope this info helps someone.

Best,
