I think with these guys you are getting into the serious audiophile
territory. You know the type... They have a second ring main in the house to
keep the supply clean and a record deck with $30,000 moving coil cartridge.
I don¹t think the Polysix was ever built with hi-fi¹ in mind (it is mono,
for heaven¹s sake!) however, it would not hurt you to make sure the signal
path is as clean as possible. There is a cable from the voice board (right)
down to the effects on the other side (left) and then a cable up to the
preamp on the top panel (sorry don¹t have the manual to hand). It would be
worth making sure these are firmly seated and non-corroded. Also it might
not hurt to change the jack plugs on the back which is a fairly straight
forward one to do. Also, make sure the ground wires, especially the big
black one down to the 367 are secure. I have had radio demodulation problems
(AM radio stations breaking in to the audio channel) at night when this wire
has been floating.
Unless you have a specific audio issue (hum, etc) then changing all the
capacitors in the signal path could be a very long process! If in doubt find
a friend with an oscilloscope and chase the signal from the voice to the
output and see which sub-systems distort the signal, if at all.
Cheers,
Andy
