The problem I could see is when switching off: if the bias goes down while the cathode ( rather than filament) is hot, it could lead to problems with stripping. It might not do a thoriated filamenmt much good, because you start running out of emission, but generally, their thermal time constants are much less than cathodes. 73 Peter G3RZP -- FAQ on WWW: http://www.contesting.com/ampfaq.html Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com Search: http://www.contesting.com/km9p/search.htm |
