The 16th edition Radio Handbook (1962) has a "Zero Bias Tetrode Modulator"
featuring a pair of 813s operating as grounded grid, zerio bias modulators
and claims to have 500 watt output. Page 683

I looked in the 11th edition of Radio Handbook and did not find it, but I am
about 87.22% certain that one of the Handbooks features 813s utilized as
triode modulators.

Will keep looking.

Well, could not find it in the upstairs library. Will need to go out to the
hamshack. If it is not there, I will look in the darkroom. Please say
nothing to my wife about my temporary book displacement.

OMG, another two-hobbied person (maybe three with the
books). I paraphrase James Thurber from a parody advice
column:
Q. Doctor, we have books the way some people have mice.
A. I can't tell if you are complaining or bragging.

I brag. My wife complains. Who says you can't have it both ways.

My wife is a librarian. She loves my getting books. She looks for them
for me, lamintates the covers of paperbacks and helps me "weed" the collection.

She's also a ham, so she tolerates my need for radios.
