Yes, the pi net design values for 4KW PEP are quite different to 1.5KW.
If designed for 4k, circuit Q will be almost doubled for 1.5k.
And I doubt it can be tuned on 10m with that high tube impedance.

"Legal limit" AM is 375 W of carrier -> 1500 W PEP. Whether the OM4000
can be tuned properly for that operating condition is another story.
