Hi Rich,
Noooooo, I don't think I shall.... and recalling my limited knowledge
of the DAF, I think it was more zero bias Class B (or AB2) than a Class C
creation... not considering the dynamic screen action.
I do have my own crazy Class C (also part time A & B) linear amplifier
under construction, if you caught the note I sent to Peter in response to
an envelope modulation query a couple months back. Doing it mostly just
for fun with a 4-400.
Incidently, SPLATTER, as defined as an emission outside necessary
bandwidth, is no longer permitted under FCC Part 97 neither without nor
within the Ham band in use. Check section 97.307b, October '95 or later.
The splatter "enabling" note, to which I presume you referred, that
previously followed section 97.73, before the great renumbering, is no
more! About time!! :-)
Clean signals & 73,
Marv WC6W
