Re: Phono 3 noise issues
Hi Bob.
Greg has kindly sent me the documentation which matches the units I have.
Am I right you are referring to issue 2 PCB? this is what I have.
As you say my main concern was the differences between the main voltage on the pre & phono.
I can certainly try the amp connected to the Pre output & let you know.
I'll check the wiring of the connector, but I suspect the connector had rotated in the housing when I took the original picture as I tightened it up last night.
I'll borrow a meter from work today & re check all the voltages against the test data unloaded then the circuit diagram loaded.
It wasn't obvious where to check the heater - & + pads but looking at the diagram I guess I can just check these at the regulator output & nose of D6 respectively?
Regards
Damien
