Then the problem could be a defective picture tube that has an
intermittent shorting screen or similar flaw. You could test this
hypothesis by simply unplugging the picture tube neck plug, leaving the
HV anode and the aquadag grounds in place and again wait to see if the
fuse fails. If it does go to the next tests below.

If you have a couple of voltmeters and some time you could put an
ammeter in series with the fuse and a second meter monitoring the screen
output (400VDC) of the HV cage. See if there is an inverse relation
between the current and the HV and how long it takes - then use some
cold spray (or hold a can of blowing/dusting upside down) on a few items
to see if you can find a relationship...

If you have a 38VDC supply on your bench then simply put the HV anode
cap in a ceramic coffee cup (clean) and leave it on for a while
monitoring the meters at times to see what is happening.

You might try turning out the room lights and see if there is any glow
around the transformer or on the underside of the PCB indicating a HV
leakage path...
