OBERHEIM SYNTH

Ok i visited a friend yesterday and he has received an OB8 that is in
bad shape. 

When you turn it on it plays ok for some seconds and then it starts
sounding like burned (bitcrushed basically/horrible).

When i tried to press the autotune button the first four lights
lighted but the rest blinked.

it is going to service obviously but can anyone harbor what could be
the problem (what the blinking on autotune means ? in the manual it
says voices are from that point onwards ignored but what can make them
not pass the autotune test..?)

Thanks 

Theodore.

It could be a lot of things, but the fact that it's a group of four 
voices indicates something common to that voice board.  It could be a 
bad connector, a bad summing amp or a bad control voltage specific to 
that voice board.
Or, the previous owner may have cannibalized parts from one voice 
board to fix the other.

Good luck.

I believe you might find this funny....
my friend decided finally to take this beauty (OB8) to the synth
technician.
So he tries to load it to his car. On the way howerver he hit softly a
door with it.

When he went to the technician everyhting was working as it should.
of course he left it there for testing and general maintenance however
this is an extremely good turn of events.

It's called a Roadie's Screwdriver, and the application of kinetic force to
an object's housing (including people, sometimes) does miracles for fixing
problems from time to time.
