u/Cultural-Heart-1981

So here I have a 1960s maganvox black and white table top set, it has life and all the tubes light up including the neck of the picture tube, and the dials also light up. The only tube that doesn't light up is the flyback tube which is a replacement, it's a Sylvania 1k3a, all the tubes on the board appear to be original maganvox, now It appears to have no high voltage so I wonder if maybe it's a bad flyback tube and it has maybe gone to air although it looked pretty much brand new, I'm thinking a failed cap in the oscillating part, any help is very much appreciated and I believe I took a picture of the cheesy number I may be wrong tho
