Default 6146 amp

I am trying to modify a 1 tube amp for 6 meters using a 6146. I think the
amp was origionally used for CB though it does tune up on 10 meters. It
worked OK before I removed the input circuit and put in one for 6M. The
problem is I cant neutralize the damn thing. It makes a great osc.I was
thinking of scraping the tuned input and replacing it with a 200 ohm
resistor and a 4:1UNUN. I figure this low of an impedance on the grid would
swamp out any feedback that might me causing it to osc. I have about 5 watts
PEP of drive.
