? True, Pete. A choke fire would be quite likely on 15m (&/or Ch. 40)
unless drastic measures are taken before hand. It would be a simple
matter to park the choke resonances higher in freq. by discretely
removing turns. I would remove turns only after the choke was installed
in the amplifier -- checking the resonances with the choke wired to the
anode circuitry and the choke not shorted.
- later, Pete
