Quote was between $600 & $900.
I hoped it would stay on the low side. I had sorta hit a wall with it and was unable to track down specific issues. swapping chips didn't seem to help at the time but it turned out the culprit was a number of things. The tech seems to think because of the plethora of varying issues is had that maybe it got hit with a voltage spike/surge at some point… which wiped out the transistor and CEMs (I had already replaced the two output 3360s and 3080s which repaired the dead output). It was not calibrating and voices were all over the place and front panel controls not responding.
I just figured for a synth this nice for a such a good price and with my schedule so filled up it was better to have the professionals go over it with a fine-tooth and skilled comb so I can start making music. ...And I was scared to start desoldering delicate traces and swapping out polystyrene caps and such.
I feel like anywhere else on the planet this repair would have been $500. I guess that's what I get for living in the Big Apple… as I said… this will be the last time I pay for a synth repair. At least now I can spend my free time making music instead of leaning how to use a scope staring at a broken splayed open OB.
Now I'm all in with a minty OB-8 for less than $2200.
We live, we learn.
