1. [AMPS] High Voltage with no filament supply (score: 1)
Author: mgilmer@gnlp.com (Gilmer, Mike)

Is it safe (for the tubes, that is) to apply hi-voltage to a tube without filament voltage? If it matters, they are 3CX800s. Mike N2MG -- FAQ on WWW: http://www.contesting.com/ampsfaq.html Submission

I'm trying to "restore" a pair of ARD230A amps. RF decks and PS seem OK. They both make power. The few identified problems seem to be in the control crap. Go figure. Amongst these problems, I found t

No. The SWR is the same as we go around the circle but the impedance changes. Yes, but this is the opposite of what you said above! 73 Mike N2MG -- FAQ on WWW: http://www.contesting.com/ampsfaq.html
