A? 50 ohm? glitch? resistor...and a fast,? correctly? sized / rated HV? fuse? will? save? just? about? any fault.?
Note the? part? about correctly? sized? HV? fuse.? 1A? for? a 8877,? not? 3A.
For? 3CX-3000A7? and? bigger? tubes, 50? ohms? is as low as? you? want for? the? glitch? resistor.?
HV fuse? 1st.? Glitch resistor on? outboard side? of? fuse.?
50? ohm? glitch R......? ?LIMITS? fault? current? to a safe? value.
? HV fuse INTERRUPTS? ?fault? current.....? and? typ? <2msecs.? ?
Don't? do? silly? stuff,? like a 10-15 ohm? glitch R...and? NO? ?HV? fuse......? you? will? do? severe? damage.
