I used to have an amp like this. It was (4) 572B's in GG, with a pair of
3B28 rectifier tubes in FWCT. I still have the power transformer and choke
from this amp, and can send them to you for the price of shipping/packaging,
but not until October because I am away from home. They are heavy!

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,
Joe Herdler KB0TXC
