This question is purely hypothetical and asked out of curiosity, it's not something I am planning on trying.

With all TV sets, either mains EHT, flyback or RF eht, the EHT is rectified and then smoothed, with the earlier mains EHT sets this usually involves a 4-pin rectifier valve and then a rather large condenser, such as a 0.1 @ 5,000 V DC, and then connected to the CRT.

I am just curious as to what would happen if the EHT were AC instead of DC? Would the picture roll all over the place in sympathy with the 50 c/s frequency, would the CRT implode, or something else?

I'm just curious?

Peter.
