Yep, the 19 and 30 Watt figures were for plate dissipation.

Well, an awful lot of 6L6s ended up in transmitters and other RF
applications.  There's a 6L6 variant (16??) listed in the RCA
Transmitting Tube Manual, as well as a number of Industrial/Commercial
variants.

As for "pushing" the 6L6, the best/worst I know of is one of Fred
Sutter's "QSL" versions, where if I remember he was running a single
6L6 at 600 V, 200 mA -- 120 Watts in!
