Ian and others,
What size glitch resistor would you use in an Alpha 77SX with two tubes?
73, George

###  50 ohms @  200watts......assuming  the amps sucks 2A of plate current.   Its simply I squared  x R. 
I wouldn’t use any less than 50 ohms for a glitch R.   You could also use 2 x 25 ohm @ 100 watt  resistors in series.
Its just ohms law.
