Hi all,
I recently acquired a Rodgers Cambridge 220-II organ in mostly-working
condition. I'm working on fixing the non-working parts and the air sound
has me flummoxed. I can't hear any difference between when the air sound
is on and off. (I assume that means it isn't working -- this effect isn't
so subtle that it's completely inaudible, is it?) Working from the
schematics in the technical manual, all of the inputs to the board look
good and none of its components are obviously bad. Anyone have any
suggestions? Can I even troubleshoot this without a scope?
Thanks,
Matt Roesle
