If you are talking about the trimmers other than the input network, the others
are for nulling the pass thru swr. It tunes out the reactance of the relay.
Just null the swr with the trimmers.

The QRO HF2000 amp has 25-150pF trimmers to ground on both the RF input and RF
output.
How would one optimize the settings on those?
Are those intended to tune out the reactance of external cabling, or something
inside the amp?
