RE: input/output within old oberheim vs. new

["Andy Ewen" <andy.ewen@btinternet.com>]

I fixed an Oberheim EDP with this problem, (customer had one old & one 
new).
It had been manufactured with the A10K and B50K pots reversed. I would 
check
this; they have their value printed on the top edge,
Andy.

New units have a limiter on the loop input, old units do not. If you have
the level turned up to where the new one is engaging the limiter, it would
end up sounding lower in volume (and probably compressed) in relation to
the other unit. The other unit is probably slightly clipping, however.
(that is why the limiter is there.) Try turning input vol down on both.

or, if you like playing with the ohm meter, check the volume
potentiometers, maybe they are different for some reason.
