Thank you for the heads up on the knobs! Ended up buying them, I don't mind a bit of warpage...gives the set character
As for testing the CRT, I dug out the CR-70 since I was a bit curious too. Cutoff is mediocre and does not reach the "black box" even with the control maxed, however emissions are quite strong:
I have heard much about how CRT testers cannot accurately test these electrostatic tubes, so I am taking it with a grain of salt. The tube obviously has decent contrast functioning inside the set in any case
