If the amp is a tube type amp then the amplifier also needs to be tuned.
Radio>>>> VSWR meter>>>> amplifier>>>> watt meter>>> dummy load or antenna
Turn amp on and tune it as it should be tuned, dip plate tune the load !!!!
now that the amp is tuned
with no modulation,,cw , fm mode,\ or am carrier,,key radio and amp, calibrate vswr meter between radio and amp,,,check INPUT VSWR, or input impedance to the amplifier. Adjust input tune as needed with the variable inductors or caps or whatever flavor your amp has for adjustable input tune. adjust to lowest you can get.
now if your going work warc bands you will have to fine tune the 10 meter/15 meter input for 12 and 17 meters, make sure your plate choke will allow you to use warc freq.
DO THIS FOR ALL BANDS THE AMP HAS.
As for the VSWR of output????? that is your antenna system and a whole nother topic.
