Ya, I ran into the three distinct band situation with my LPB2-20, which was set for the low band, about 540 to 810kHz, or some such.
I was able to get the needed information about re-building the output circuit, 3x toroid inductors and 3x capacitors, and made the conversion.
The output filter section is the same for the 20 and 30-Watt versions, maybe also for the 5-Watt.
I don’t know yet if I “won” the LPB-AM-5…. I’ll check tomorrow.
