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
