I mean, really... in MY case, I've got a pair of 250TH's in push-pull,
link coupled... and in order to
keep World War III from occuring in the neighborhood, from the hours of
6AM to 12Midnight, I
limit my power output to 100w of carrier. ONE HUNDERED WATTS OUT, from
a *pair* of
250TH's. down to 1500v on the plates, 100mA... hell the modulator is
dissapating more power than
what the final is. (another pair of 250TH's w/1500v @ 100mA bias)
From Midnight to 6am, I endulge my 'high power' craving by shoving the
link in, until I reach 200w
of carrier output. The final tubes -still- don't know that they're even
on, but with a full-wave loop fed
w/450ohm ladder line, I've gotten some good reports from fairly distance
places (like Skowhegan, ME).
My plan, all along, was to run the final around 1500v @350mA, and then
modulate that, with the 250TH's
at 3kVDC, biased off at 150mA. THEN, those tubes show some color ;-)
but, alas, that's only into a dummy load... only 200w output, durning
self-imposed quiet hours...
and I still get complaints about that.
Had a neighbor, at one time, call my house at 3am, to tell me I was
screwing up his TV (on rabbitt ears, in his garage, while he was doing
machine-shop type work, with drills and lathes and milling machine
running into my bedroom window, was is next to the garage he was in). I
said "I don't get on during the day time, except early morning, and even
then, the power is limited... and it's 3am in the morning, I can't sleep
because of the noise you're making, and you're bitching about me messing
up your TV that's on RABBITT ears? WHEN do I get to enjoy -my- hobby?"
I hung up, and he apologized the next day.
