More Info:
I am not sure as to the operating parameters of the 3-500z for L-7, but here
are the way the tubes are run in the L-4B:
CW-Tune: 1900V (no load) ---- 1760V @ 560ma (under load)
SSB : 2600V (no load) ---- 2400V @ 800ma (under load)
The Idling Plate Current is as follows for the indicated tubes in a DRAKE L-4B:
Tube CW-Tune SSB
Amperex 8802/3-500Z 100ma 160ma
Amperex 8163 100ma 160ma
Eimac 3-400Z 110ma 170ma
Eimac 3-500Z 170ma 260ma
73,
