Yikes, I hope they paid for it. I did a complete PA rebuild with newer devices a couple of years ago, even though just the drivers were bad. Came in at arund half that, IIRC. Generally, the PA is pretty bulletproof, but reverse polarity is a killer. They must not have had it properly fused if the suicide diode didn't save it. 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
