How does the amp know when its tuned? Does it use shutter (choppers)
wheels to determine position or does it use variable resistance.. If its
hunting for a match, its prob not getting the signal to stop because the
needed feedback is not going to the processor. If the amp is trying to
logically locate a match I would most likely rule out the processor and
eprom. Look at the tune circuit and where that ties into the processor board
or the check out how the processor knows where the tune is in relation to its
position... Regards... Richy
PS since you disassembled the gears, make sure the vr's (if used) are
"retimed" to the tune cap. It may be searching for a match but the tune cap
is way off from the resistance position causing the units to hunt. If it uses
choppers make sure that is lined up since the processor may count pulses to
determine location from a predetermined stop.. Hope this makes sense :-)
