Doug,
The reduced power is a consideration for the internal tuner relays, not
just for the PA transistors.
If you have the internal tuner installed, that power reduction is
automatic. For the K2/10, it is 2 watts and for the K1 it is 1.5 watts.
If you are using an external tuner, then manually reduce the power.

In learning about my new-to-me K2, I find that there is discussion about
automatic reduction of transmit power during tuning. Does that apply to the K1
as well? The K1 uses the same output transistor as the K2, but in a
single-transistor class C configuration, compared to the K2 which uses two of
them in a push-pull configuration that can put out more power and can work with
SSB. But at 5 watts, I would think the K2 transistors would be less stressed
than the K1’s.
Is it worth manually setting the K1 power down to a lower level when tuning, in
order to avoid power transistor problems? Both my radios have the internal
tuner options.
