Interesting that you mention this.
What, in your opinion, are, say, the two most-easily serviced 2trk and 4trk quarter-inch Tascam reel machines at the moment?
A Studer a827 is sooo full of specialized eprom microprocessors etc, that I really worry about anyone owning those longterm.
On the other hand, Chris Mara can fully restore a jh24 to run for the next 50 years via parts from Walmart
As I've mentioned around here over the years, I was one of the first 10 US authorized dealers in the 70s for 90-16, series 70, 80-8, 25-2 etc....and then on to the later machines as well as for Otari.
At this point in time, I'm thinking of grabbing several 2trk, 4trk machines strictly for creating down-generation dumps back & forth from the daw.
I also still own a couple of tsr-8s (which as I remember you don't like) that I still love for their synchronization capability in the compact size. But they are actually a little too pristine sounding for some of the dump projects.
I can certainly get grit via 4-6 passes through a 3340 (non-solenoid) or 80-8 with n/r off. But I'd like to keep things to quarter-inch and I don't really ever want to deal with 3340s again (oh how many times I had to send customer 3340s/2340s out for servicing).
Opinions? By the way, I'm in LA. You're in Chicago, right?
I used to visit Montebello regularly. Knew Chang etc. In fact, one afternoon, Chang and I sat in the lobby while he hand-drew resistor changes on one of the foldout schematic pages for an 85-16b so that it would do 30ips (which I did and then un-did a few weeks later) as well as he (and as I remember a guy named Rick was sitting there as well) troubleshot and corrected two 85-16bs not synchronizing correctly.
I had both 85-16 machines up there (as you remember, they would dismantle enough to throw in the back of a car), those ungodly snakes of umbilical cables, the autolocaters, if-1000 and all those split-out cables that had to route to four diff connection spots, plus the synchronizer.....it was a nightmare!
But Chang got them to work! Specifically, neither one liked to revert to ext sync slave. At the time, Chang and I discussed how I had been in NY for the 1977 AES and Tascam had two synchronized 85-16s there in the booth. He scrunched up his face and said "yes, well we didn't implement sync the way we needed to, but we've got that corrected for future machines".
Which, imo, they did end up implementing beautifully for all the future machines after ms16.
