Not sure. Radio Handbook, 17th edition page 682, Utility 2 KW Linear pair 813's GG, also Radio Handbook 23rd edition page 17-6 An 813 Economy Amplifier for 160 or 80 meters pair 813 GG. Most of the other handbooks show the tetrode connection that would be applicable to any tetrodes including 813 which would be grid driven. Hope this helps. Mike
