Ooh. Well, I hope it wasn’t punishment for “bending” the NAQP rules: "No greater than 100 W. Use of external amplifiers capable of more than 100 W output is not allowed." And yes, my KPA is not running while I play in NAQP...
OK, so please send me a copy of the fault table for evaluation. We will see what we can do, but I suspect we will need to get you in touch with CS on Monday. I am sure I will hav emote questions for you after I go through the file.
