Hi David Lawrence do you use the grid choke on the input tube or the finals tube? What brand and value?
Also did you use AC on the heaters of the 300b before switching to DC?
Are you using AC or DC on the C3M? Did you raise this tube above ground using a the center tap of the 20V filament transformer?
thanks
