Atwater Kent 55F
#20

Thanks!  I don't think it's worth adding AVC to this.  I'll keep it "somewhat" original. Not fully since some mods had been done in the past and in playing with it, I've done further changes in the resistors to get bias and plate voltages a bit closer to the specs that I have.  It's playing pretty good, though it seems a bit more distorted than other radios I've worked on and tone quality is less than stellar!  I don't know if the universal interstage audio driver transformer has anything to do with that, but at least it works. I did calculate a series resistor for the line voltage and it's not as bad as I thought it might be, so I ordered one that will get the line voltage down to 105 vac or so.  That seems to bring things down to a reasonable value.  This radio will spend virtually all of its time sitting an a shelf looking pretty, and, as I said before, will only be turned on for a quick demo.
