[Johnson] Ranger I problem

My Ranger was completely refurbed and has been working properly.

I put it on the bench to reset the bias and keyer settings, while it was on 
the bench I finished the PTT wiring (ala Phil Salas and WA1HLR).


While testing it, I noticed that one 6L6 metal modulator tube was running 
considerably hotter than the other (laser thermometer)  Substituting glass 
6L6's showed a slight glow on the plates of the tube in the same position.

Then, in AM,  the Ranger started to "talk" to me and I can't quite isolate 
the source.

Resistance and voltage checks are OK.  Before I start to take it all apart, 
any ideas??????

Tnx in advance,

Jim
