I actually replaced the 6K7G twice. The first time, the set came up gradually but the reception was very weak. I turned the radio off and attempted to remove the tube.

Next thing I knew, I was standing there holding the glass envelope of the 6K7G and the bakelite base was still in the RF unit.

That was fun to get out of there. Not.

So I tried another 6K7G and all was well.

The 6K7G I had in the 37-670 to begin with went into the round file along with the one that came apart on me.

p.s. my tube tester (Heathkit TT-1) has no headphone jack either...
