Clean all the wires to it & the "cup" also. Put back together with
the new 3CU3 & try it.
BTW dischage the CRT AGAIN before reassembly !
BTW #2 most HV rect tubes DO NOT have a filament glow !

I'd also clean the regulator socket and cap above the cage - it has full 25KV on it and looks as though it may be just as dirty, judging by the plate cap.

HV loves and attracts dirt - it's a much lower resistance/impedance and may be your only problem.
