The socket on the rear is not mains but an audio input via the left hand potentiometer, 650k ohm, which is crudely wired as a rheostat to the volume control in the grid of the 6V6G output valve.
Its all messy screened wire so I will likely remove it all before trying power.
The mains transformer I have checked with an ohm meter. It has a primary of 27 ohms, the 6.3v, the 5v and the center tapped HT winding all show the expected resistances. The knot of unconnected wire under he transformer against the back of the chassis look to be unused primary mains voltage tappings.
Isn't life better when you can post pix?
Thanks all for your interest and input.
More will follow............
