Did it ever work well on 12M? If not or not tested Id also suspect the plate 
choke and hope the big Ameritron fits.

As far as the LF oscillation I hope the bias is not fed thru a RFC as these 
tend to turn the tube into a TNT ocillator. I also suspect the antenna choke 
is open as that would likely be self resonant down there.

##  U mean the safety choke that is in parallel with the load cap, correct ?  Typ 
2.5 mh.
