JUMA PA-1000 on 4 meter possible ?

[PE5TT]

Hello,

I still got a 9th order LPF for 70MHz capable of handling 600Watts lying around here from another project
I wonder if its possible to make a few hundred watts with the Juma PA1000 setting the band to manual and selecting “AllMHz” and connect the LPF filter behind the JUMA PA-1000 ?
Except for the bandfilters the design of the JUMA PA-1000 all seems to be broadband. Could this be done safely ?
