[Amps] Metron MA1000 vs MA1000B

[K6QD]

I have recently acquired a MA1000 which included a manual for a MA1000B.
BAMA has a MA1000B manual but nothing for the MA1000.  It is my current
understanding that the difference between the two PAs is only the bands
covered; MA1000: 10-80M & MA1000B: 15-160M.  This difference is implemented
in the output filters only.  Can anyone confirm my understanding and/or
provide some MA1000 documentation? Tks es 73, Mike
