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!
