Yes, exactly my problem Perry. Where are the reed switches located, on the bandpass filter board?

Check your collector current on the bands with low output. Is it the same
as the 80 meter reading with full output?   If so.....

Check your TX output bandpass filter reed switches.  Check to see if the reed switches are off on the bands not being used.

Typically this problem is caused by reed switches not being turned off or just stuck on when not using those bands, causing a heavy load on the final and low output.
