Hi Darrell, I have owned 2 of those amps. You can't own that amp and not be
an amp Guru. The amp is lacking BIG TIME in a lot of areas. First off, the
cooling system is a joke and that is why it overheated on you. Lets put it
this way, I can tell you in less words what is RIGHT with the amp than what is
wrong with the amp. What is right about it is that it is a nice shade of black
and that's it! I severely modified the first one I had and then it worked
better, but I practically rebuilt the whole thing. I used a solid state timer
in place of the tube timer. I added a bigger blower. And the list goes on and
on and on. Not to mention it lacks a tuned input circuit. That's OK if you
are running an old boatanchor "tune it up" exciter, but a new exciter...I don't
think so. I had to use a small tuner in front of it to get it to match. I
have all the mods that makes it a better amp. Its basically a total rebuild.
Good Luck. 73 Louie
