3-500Zs have >2 x the voltage and emissive capability of the 811A. They
also have less grid-lead-L, so they tend to be less squirrely in g-g
service.

A 20A, 120V mains circuit works ok and the power difference is small on
SSB.

The tank is designed to run with 600 - 800 mA peaks.

In good condition with the needed mods, they are worth >$1200. These
mods are covered in an article about the 922 on my Web site.

But no one at the RX end would see the difference.
