I haven't tested any audio functions (though I can see meter activity for all 8 tape tracks in PLAY), but it would seem I just picked up a straight-up, no jank happily functioning 388...2 PGM meter lamps are out, but all other indicators work, and all transport functions work...the rubber seems in good shape, and the rollers all roll quite nicely. It is relatively filthy, but should clean up nice...very little in the way of scratches, scuffs or dings on this unit. I'm surprised. There were some service records from 2000-2002 included with it...more on that later. It's just a nice, straight and complete unit.
The tape path looks good! Almost too good...hm...maybe the R/P head has been relapped...more on that later.
When I was presented with the "instructions", my assumption the manual was a photocopy or a hard-copy print of that horrible quality pdf that's here and there on the internet was confirmed...a generic 3-ring binder:
BUT...open it up and bingo, original bound factory manual, with the fold-out tabloid schematics!
And the remote? A proper RC-71. A bit weathered...needs some cleaning up and a new strain relief grommet, but all the pins are straight and present on the plug.
And there's more...
A punch in pedal,
...some vintage rack gear (Alesis MIDIverb, BOSS RCL-10 and BBE 362...the first two are without power supplies, but I'm not worried about finding something that will work...
And that's not all...
