11M test just now showed over 400w AM from a 1970's 23 ch CB barely powered by a 12v, 2 amp bench supply. Amp still on work table so I was only using one plate transformer (1800 400mA). That's a best ever for 27Mhz especially given I did not even tweak Tune, Load or RF Input, just took a good guess and as the first try I used a 6A mains fuse. There's much more potential here. Tickled silly to see it working above 40M. These 4cx300a tubes are amazing for their size. Time to put the bottom cover back on and prepare for a full power test and maybe even use if it holds together. It was a good day.
