Checked the board and chassis again today and finished all soldering. The back buzz has gone now completely however there is mains hums albeit very much in the background unless the volume is turned up to almost maximum. Is this now purely down to the circuit design?
I have to make any other additions to see if can make any improvements at all.
Best Regards
