Behold, W7CXA signalled from keyed 4-1000A filament:

Anyone remember a three tube AM mobile rig for 80 meters? It used a
6146 modulator, a 6146 final, and I think a 12AQ6 oscillator. I built
one and it worked great. I would like to find the schematic for that
little rig.

Was that the one in the 1965 ARRL Radio Amateur's Handbook?

If so, I have it and can post it on ABSE.
