Some time ago, mention was made about using an MOV near the power amplifier 
tube as protection against transient surges, perhaps in the filament area.

Looking at Mouser's MOV selection, the reader is presented with a plethora of 
selections, each one having a 1MHz. capacitance listing.

My question now for the reflector is would the inherent capacitance in an MOV 
mounted near the final and connected to the wiring going into the tube have an 
effect on the circuit because of the device's inherent capacitance, or should a 
Metal Oxide Varistor not be used at all, with a better choice being perhaps a 
gas-filled device?

Comments?
