Thanks Jazz P Bass and g-one for readable schematic and final take on it. I`ll get local E/Tech to change out U6/CD4051BE,
if you both agree, that`s the way to go.

Just checked my TP 10 & TP11 readings , found some looking strange, this time :-

TP10 Chan1 FX ON = 2.75 dvc FX OFF .12 dvc
TP10 Chan 2 FX ON = 2.40 dvc FX OFF .72 dvc

TP11 Chan 1 FX ON =2.75 dvc FX OFF .94 dvc
TP11 Chan 2 FX ON = 3.38 dvc FX OFF 1.58 dvc Amp Bias 36mv 240v UK

correction to above TP10 Channel 1 FX ON is 1.81 dvc. So will now replace U6 and report back on outcome.

You boys were right on the button, my UK E/tech just rang to say U6 chip WAS the problem and unit now works perfectly.
Thank you all for your kind help, my regards too to Chuck H. Best wishes, XDaddict.
