Around trip of 547 miles and I have 5 CRT's
There are two MW36-24's of which are of interest to me, I never remembered the sticky out final anode on my Ferguson.
A 17 inch Cossor which I believe is a 173K, I wonder if this would be a back-up for the 17 inch Murphy I have yet to attempt the V280.
An unlabelled 14 inch tube and
A circular tube 12.5 inch diameter at the screen outer that is a reworked tube by Nuvac I think the label says Mazda either 122 or possibly 622, any other guesses?
All appear to have a heater resistance of close to 2.9 Ohm cold and no measure shorts when just using a DVM. When I asked about the background of the tubes I was told they were found in Mum and Dads loft, a house they bought from someone that was a TV engineer. So nothing of family interest to the seller.

Round CRT
Tomorrow will be me cleaning the pins and me checking emissions as above and comparing to the tube I have in my Fergy.
