Subject: [Amps] Need some amplifier advice
<Hi All,
<I am looking either for plans for an 80 meter mono-band amplifier optimized
for the RTTY portion of the band or an actual amplifier itself. I want an all
tube amplifier, including the power supply. I want no solid state components at
all in this amp. I would like <it to be very "overbuilt" so that when I run it
at 500 watts RF power, it is just idling. Of course, this is for RTTY, so it
would be continuous duty at 500 Watts. I do not want to operate any higher than
about 5oo watts.
<I would like full metering. It does not need to be rack mounted, but I do want
a rugged chassis, and excessive ventilation to keep the tubes safe and so that
those tubes last a long time. I do want it to be fully enclosed to keep four
and two legged children safe <from the lethal voltages.
<Any ideas or locations for plans would be greatly appreciated.?
<Thank you so much!
<73,

## why mess with tube rectifiers ?? That implies using a full wave
center tap config.... which is a dead loss imo.
Then u would also require the mating fil xfmr for the tube rectifiers... which
has the B+ coming out of the CT of the fil xfmr.
Its not 1956 anymore. You cant blow up 6A10 diodes, nor 10A10.... or
10A07s.
