I have schematics for the 550A but I couldn't find them for the 550B to verify the pinout.

Can anyone verify that the 550A and 550B have different pinouts?

If anyone could point me to the 550B schematic it would be greatly appreciated.
Thanks!

I have 550, 550A and 550B EQs all in the same rack, no problem. I think the only one that had a noncompatable plugin issue with the current racks was the original 525 limiter.
