I had this amp (sb 220) for several years and it had always worked
fine. Moving I put it in storage on my new property and 2 years later
when I set up my new ham station...no more 10 meters. All the other
bands work fine with full power out. Looking at the band selector it
also looks fine not burnt out. The bad thing is I run 10 meters. Any
one have an Idea or have come across this problem....please let me know
with some testing ideas.

Thanks Sam

Aside from what other posters have mentioned, there's another area to
look at:

the tuned input coil circuit for 10 mtrs. This is the tuned network on
the input side of the amp. check its bandswitch contact, the input
coil for continuity, etc.
