Why not just try to deal with his request or otherwise stifle the urge to reply.

Id suggest 3B28's in placeof 866A's however, a direct swap.

<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!

## 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.
