RE: mono block ground Loop?

Bill:
I am not getting hum, though I am getting distortion in one amp after the above mentioned wiring, A-B'd the Integratated mono-blocks, definitely not the same output now.
I bought these heathkit amps (AA-18) as a mono project , as the plot now thickens, now that I have two.
I hope it is not the transistors.
All I wanted are two identical mono amps, sounding the same.
I am a vintage nut, not being a trained tech is killing me.
I worked at a TV shop during High School, 47 years ago, I should have stuck with it or perhaps paid more attention.
Now I am listening to a Sony PS1 into a AA-18, thru a optimus pro LX5
with the Linaeum tweeter. a set of Kenwood KH-51 (football) headphones Not much money invested all of this.
Thanks in advance for suggestions.
