I have got serious druthers about that "Hiss" ! The Hiss
is a sharp point or contamination of the surface at Anode
socket that the HV is getting out. My 'cure' was to very
thoroughly clean the surfaces around the Anode connectors
and replace the anode cup and then plenty of clear silicone
to seal all and be DRATTED sure the Anode lead IS CLIPPED
into the Anode socket of the CRT. I haven't found any
shortcuts other than above and would dearly love to find
such. Also be sure the Dag is grounded good and all grounds
in place. Rebuilt CRT's could have a fault for that. That
Hiss can cause what you describe below.
