Tube but not BA Yet

[Bob Peters]

I have a Kenwood 922 Amp that I just purchased and need some help...
Just put it on 75 meters today and Tunes great to 1KW out with
100watt drive...Only problem is that it is in the 40 meter range but the
band switch on
75...Tunes great on 40 with the bandswitch on 40 and in the 40 meter range...
Whats wrong????Don't have a spectrum analyzer so can not check for spurs....
