The one described in the RH is a "split anode magnetron".   The note on
it says that "frequency stability is not very good:.

There's also a discussion of the RCA 825 klystrode--a sort of klystron
triode hybrid.

It's my understanding that the allies used the cavity magnetron and the
axis used klystrons for their transmitters.
