Operator Error !More pictures would help. That small shot does not tell much.

I had the Ground wire from the fz Generator going to the the ps cap (ovdc) and/or the speaker ov
I moved the ground to the RCA Ground input and it cleaned up the wave , Cant ask for a better SQ wave?

also I don't run the RCA inputs levels very high, But when I do, should I get worried about the hi-pitch sound from the input Transformer?
Looking into the speakers next which are low Ohm.
