Sam, all you have said is it is not working on 10. Could you provide a
little more data?
I will help with a little logic:
Are you getting grid current when you drive it?
If no, then investigate the ten meter grid tuned circuit and bandswitch
(good luck, it is buried behind the front panel.)
If you are getting normal grid current, but zero output, then what about
plate current?
If you are getting tons of plate current but no output THEN you could
suspect the bandswitch.
