Have you perchance tried a set of 'out of the box' new tubes in it?  Most 
amplifiers never oscillate, however, some apparently do.  .  .  24 Space 
Shuttle went off with nary a hitch before the glitch.

Whoever is forcing you to read tiresome drivel should stop forthwith.

Whatever is causing the Tune C to arc in Kevin's PT1000 is unlikely to be 
anybody's "pet personal peeve", Mr. Pruett.  Kevin would like to get the 
problem fixed.  Based on the circumstantial evidence, I'm guessing that 
parasites have taken flight.  If I am wrong, I will be laughed at.
