[Heath] SB-200 and AM

[jerrylofstead at bellsouth.net]

Oh yes! Controlled carrier the RF level varies at a voice rate.  DSB SC(supresed carier) was produced by putting two tubes in push-push...  usually push pull grids and paralell plates. Audio was applied to the screen elements. I ran dsb for a few years since as a kid, l could not afford a ssb exciter  ACentral Electronics SB10 OR 20Watt SB 20.  These were the first available in the mid 50s.  DSB SC workrd great.  Google tht CE exciters for early SSB.
