New issue...
Put the chassis back in, fired it up. HV is clearly working, I can see blue glow from the shunt regulator. But when the anode lead is connected to the tube, I get this sizzling sound like it's shorting to something. I'm reasonably sure I have the CRT installed correctly: anode clip, rubber boot, mumetal shield, retaining bracket, ect. Anything that could cause the anode to sizzle that I'm not aware of? Tried another HV boot just in case it had a hole or something, same result.
