Pull all the tubes and see what happens. Take due precautions to make sure the
HV is discharged - I pull the power lead out of the wall, give the HV a minute
or so to discharge, then put a resistor of 10 watts and between 1 and 5k
between HV and ground for a few seconds and then put a clip lead HV to ground.
Pull tubes, remove clip lead, and power up.
Does it blow fuses then?
If not, discharge HV as above, insert tubes one at a time, if it doesn't blow
fuses, discharge HV as above and change tubes to find the one that caused it -
discharging each time.....But probably best to change all the tubes.
