Just checked the fan, it is fine, turns on with the amp,
and blows air forward through the front vents.
Understand extreme heat, I've used this amp setup
in Tucson during the summer at 105 + degrees with
no problem. Amp is rack mounted in a SKB deep case
with a space above the amp for ventilation, nothing
So, it sounds like your description: amp turns off,
takes about a minute to cool down, then works until it shuts off again
If my fan is OK would bad power create the same symptoms?
I thought bad power would just not allow the amp to
function rather than shutting it off.
One thing, I did feel the front of the amp, and towards the
right side, above the potentiometers the ventilation slits
seemed hot (I've never checked before, might be normal
as I've never had any problems.)
In some ways I wish it were a bad fan, fix it, done.
It's the uncertainty . . . . . . . .
