What exactly is this QSC RMX0002 (turn on delay) and RMX0006 (FET). Might anwser some of my questions.

Cannot access this info. They display other info requiring a lot of tech work.

When were they issued? I let my QSC affiliation lapse a while back.

Looks like 2002. Some of the solutions to problems mention in the RMX service manuel refer to incorrect parts. The Qsc forum talks about his alot.

Just wondering what was found to be defective mentioned in these bulletins. The 2450 seems to be very troublesome.

Old thread.
New reply.
I just ran into an RMX2450 that had a rail switching FET fail & Q205 had a broken lead.
RMX0006 covers the higher rated FET replacement (MTP52N06V)
RMX0002 is a zener diode mod: if the clip led stays on for 10 seconds at power On.
RMX0001 is for replacing Q205. (The leads break.)
