Reel to Reel Tape Machines / Re: update on Studer A-820

update;
Fred has suggested 2 changes/updates to my A-820;
one is a Single-Head Reproducer.....Fred explains.
"The stock machine (like yours) had, in order, an erase head, a record head, and a reproduce head.
Any tape put on the machine is then dragged across the faces of all three of these heads.
We think this is really dumb, really bad, especially if all we actually need to do is PLAY a tape.
So we remove the erase and the record heads, move the repro head to a new position, add scrape flutter reduction rollers, re-adjust the running tape tensions and then discover that it all sounds so much better because we have just eliminated the scrape flutter excitation caused by the unneeded erase and record heads. (And we also reduce the wear on our valuable tapes!)
So, that's the concept behind the ATAE SHR (single-head-reproducer), in a nutshell."
in addition to this recommendation, Fred also recommeded something called an 'external calibrated azimuth control'.....which is like VTA for a tonearm. it will allow quick and easy adjustment to the head azimuth.
i'm planning on having Fred modify the head stack to SHR, and add the azimuth control. then he will load the beast into his truck and deliver it to me here in the Seattle area. i will get to watch as he sets it up.
i can't wait.
