Thanks for all of the tips.
I WILL DO EXACTLY as you say and follow your instructions. I most likely will be doing this on Monday of next week. I will get back to you via this forum by Tuesday and hopefully I can tell you I found and solved the problem.
If I do find the problem by doing what you have suggested I will owe you a beer!
Ugh that amp is so heavy!
Thanks again
And please check the forum on Monday or Tuesday for the results.

PS I don't believe the amp is still under warranty. It's better than five years that I have had it.
