I'd write or call Ameritron/MFJ and ask 'em directly. I have an '811H and
I'd be interested in knowing as well!

When I received new 811 tubes from Ameritron, after burning out two of
them,
they sent along small resistors (?) with the tubes. They did not explain
what these were for. Can anyone out there help with the procedure for
replacing the tubes in this model linear?
