Hi All
First Post here. So hello to everyone.
I have aquired some Studer machines... been in a basement for approx 15 years.
The first one I'm having a problem with ia a B67 Mk2 (B67-2-2.00 MK2)
Tape path cleaned prior to use. All in very good order
When powered for the first time the unit played back tape through the onboard monitor speaker.
The next day there was no output from the speaker, although there is a slight hum from the speaker at ful vol. :-(
Other transport control functions seem work correctly.
I've been looking through the service manual to check the supply voltages to the plugin boards connected to the basis board. the -12v is present at the board. but it doesnt get to the plugin cards (Pin14?) connected to the basis board. All other supply voltages seem to be present 5v,12v,0v. on the plug in cards.
I've tried to follow the pcb track, but I cannot see where the track should go..
Any Ideas??
My eyes are starting to go fuzzy looking at all the green pcb track.
regards
