How hot does the (tube saver} varistor usually get? I am restoring an aa5 that is working ok now eccept the varistor gets very hot, hot enough to sizzle water. I understand the princible of holding back the surge but if the high heat is not normal can it be replaced with higher wattage resistor without damage to the tubes?
Thanks, Todd
