[Milsurplus] 800cps inverter on Craigslist in Portland

[howard holden]

First you'd have to find an 800hz step-up from 80 to 120. Good luck with that! Easiest although not "politically correct" is to just build a 60hz supply with suitable voltages and bypass the GO/TBW/GP supply. You can key through the filament center taps. Works well with my GO9.
