Well

Tried to align. In the process found more bad soldering.
It roared when peaked, hummed and overall behaved badly. Reception was the same - lots of hum.

Eventually I decided to do what I wanted to since the first day of looking at it. My number one suspect was cap C3.
It is supposed to go to the B- but somehow was connected to .... the Hot plug pin.
Kirk!!!!
Kirk swore all the caps including this were connected this way. I trust the fella.

I connected it to B-.....then realigned it and now it works quite acceptably.

I still want to see if there are more bad connections by tapping and probing but it is more than I hoped for for today.
