I would suggest that the type acceptance requirement for the amp would MANDATE that it not be usable on 60 meters since the maximum allowable transmit power on that band is 50 watts ERP.? ?Just like the 27mhz lockout is required.? Using this amp on 60 meters would be illegal.

Please find below an excerpt (highlighted in bold/italic text for clarity) from Page 5 of the LA-1K Technical Manual for your consideration, Steve.
BAND SELECT To switch bands (160M, 80M, 40M, 20M-15M, 12M/10M, 6M) press the BAND button on the touch-screen display then select the desired band.
As can be seen above, 60M isn't a band available on the "LA-1K RF SENSING 1000W DUAL HF LDMOS AMPLIFIER" currently available from Palstar.
Thought you might have, for example, modified the firmware on your LA-1K amp to allow it to work on the 60-Meter band.
Oh btw, 6M (labeled 50MHz by some manufacturers) is an available band on the LA-1K, so I am not sure why Palstar would exclude 6M in naming the LA-1K amp because HF doesn't cover 6M.
