[Elecraft] KPA500 Main Power - ON 24/7/365?

[Jack W9JH]

Is there any harm in leaving the KPA500 rear MAIN Power Switch ‘ON', 24/7/365? (not the front panel power button).

I have done that with my KPA500 at the home station with no problem, but wondered about doing it at the remote site? I can operate the front panel “ON” button and “OPER/STBY” switch remotely so the amp is not running full-time, just the internal power supply.
