Change the choke out for one of the Ameritron ones, that way you know it
will not resonate on 17m or other WARC bands. RF Parts sells them for about
25 bucks as well.

Be very careful when trying to use standard amps that were not designed for
WARC bands. The plate choke is series resonant around 18 MHz in many amps.
I'm not sure the TL-922 configuration but you may apply 18 MHz energy and
the amp will make a noise like a cherry bomb just went off. And you know
what that means.......
