A better way to use the 813 in triode mode is to connect the two grids

That is the way I am using them. Got it all together last night and had
a short QSO with a good audio report. It takes very little Ranger
audio to get 100% mod.

Unfortunately, the plate tuning cap started arcing so I had to shut it
down and have a look today.

Please post a schematic on your web site!
