greetings all,
finally I got the mechanics working - now have to tackle a hum through the tone arm-cable connection !
I am working on a BG6000 that came without the CD4-preamp board - also missing is the mute circuit !!
there are too many wires on the connector, which was originally wired to that missing board #6,
meaning I have to connect directly to the outgoing 5-pin DIN plug cable.
looking at he circuit diagram I should only connect the wires for FL & FR, common ground and chassis
meaning PIN# 1, 9, 7 and 5 as all other wires serve no purpose in this case ?!
could someone confirm that or correct me.
I opened the DIN plug to make sure none of the wires have come loose as a possible cause of the hum- all checked out fine !
perhaps there is the possibilty of a faulty cartridge ??
thanks for your support
ALF
