Well.
Decided to look at that panel. It is for 6A8 tube. The guy used one metal which would not fit through the base.
So he cut it off, having left small pieces riveted. I looked if he provided the grounding for the pin1.....sure'nuff, he didn't.
I worked aroubd it - I soldered a piece of multistrand wire to the piece of the base that was left, scraping it well and using the plumbers flux for copper pipes. The other end went in the hole for pin1. This is a good reliable GND.

Put all tubes in except the rectifier ones, connected the cables, measured 5V filament and high voltage, saw all tubes lit.....good.
The rest is either Friday or during the weekend.
First have to clean all shields - they are dirty.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
