i had my system on today and i noticed there are 6 leds on the board of my original ms2250 but only 5 on

never noticed the other 2 before that appear to be unique to the ms2250 but the one on the right channel is not lit, is this something to do with it being brigded?
odd, even odder i never noticed them before

Second internal clip led, left out on later models "Same as the other clip lights just on the board" C

YUP ! comes from over driving the amp into clipping till the dang light stays on permanent it seems
Or your amp could be telling You need two amps

odd, i very rarely spank my subs that much as it's set up for pure sq!
don't think there's room for another amp

wow, i have rev b and seen no 6 leds ever on my board.
that looks to be a later rev board since the amp came out later in the
ms line up and the speaker termianls have the screw down terminals
and also the braided wire.
interesting...............thought i seen it all.

All the boards I remember have the component holes, you just have to stuff the board with the missing components. Nico's 2250 10th has the component holes also just no resistors and LEDs.
According to my notes and reverse drawings these are nothing more than a on board clip indicators. PG decided to leave them out of most amps I have seen, but it can be added for those when the amp is inverted and under plexi. C
