There seems to be an issue with the suppression capacitor on these - see - viewtopic.php?f=17&t=70455
- As for the missing channel - that should be a simple continuity issue. Do you have a test meter? Presumably it was advertised as fully working?
I still need a little Help please...
After installing the switch snubber circuitry as described by Coffee Phil in the previous thread I have a new strangeness going on...
The popping of the speakers has been completely eliminated, HOWEVER, when the TT is switched off, the motor is oscillating. That can't be good for it, or the belt... and is no doubt using electricity when off.
I have noticed in the process of this that the switch board doesn't resemble the schematic in the service manual, or the images posted on the other thread... what on earth have I got here ?
[pls ignore the the black and brown wires coming away from the switch. I removed the snubber I put on and those wires are currently going nowhere.]
