I would like to have a copy of that article; for I found an old homebrew transmitter recently that uses a pair of 807s to modulate an 814. It needs a complete rebuild, and I have not put power to it yet. The bad news is that looks like it has been sitting in a barn for the last 30+ years. The 814 has a rated plate dissipation of 65 watts (is cheap and plentiful) and will fit in an 811 socket... or so I hear. The modulation transformer looks like it came out of an ARC-5. I suspect that this transmitter may have been built from a handbook article, but I don't have a HB that old.
Any thoughts? Mike /kz5m --- crawfish <[EMAIL PROTECTED]> wrote: > I just received a copy of the 12th Radio > handbook(1949).
