Don You are correct of course, about the non specific 807 to 833 relationship but this would be true also if in push pull transformer or link coupled driver, AF or RF. Either one of the 833s will see the energy arriving from the secondary of the XFMR coupling and does not care which driver tube developed that energy as they are added in the XFMR. However, it is different in the modulator of some BC equipment where an 807 is a direct cathode follower to drive a specific 833, and there is no driver XFMR.
