[Amps] Henry Repair

[Dennis OConnor]

While you are in there install a fan to blow on the ballast resistors... The reason your ceramic mounts break is heat build up on the resistors where one end of the ceramic is HOT and the other end cold... Ceramics don't like that...
And while you are in there inspect your ballast resistors,,, Any that show a band of color change on the glaze need to be replaced before they fail - unless you are into emergency repairs...
And if you have not already, arrange for the 220 power to the amp to be OFF when you are not using it... The low voltage supply for the relays is on all the time, leading to premature failure...
