Hi,
I'm restoring a Yamaha PC2200 power amp. i use (isolated) rca jacks instead of the unbalanced input jacks.
This amp is "class II" equipment (european version), no safety ground involved. with that in mind:
i have two sowter tranformers, type 3575, which i intend to use as input transformers.
does this make sense:
Primary:
XLR Pin 1 -unconnected
XLR Pin 2 -RED
XLR Pin 3 -ORANGE
RCA Hot - RED
RCA GND - ORANGE
Secondary:
WHITE - Signal Input's CH A+B
YELLOW/BLACK - Signal GND's CH A + B
I am not sure if this works because with no safety ground involved the Signal Inputs on the Amp CH A+B would be "floating" with no reference to ground - right?
Appreciate your help / thoughts,
Best Georg
