Thank you for the picture of the 817 Steve. The tube is a Hivac T5M 5 inch with electro mechanically focused and scanned. Some sets had Mullard tubes fitted with a 6.3v heater.
The 817 uses side contact EF6 valves and is a vision only set.
I did talk to Gordon About the set and the 9 inch console which he also had restored many years ago.
Mark.
