Also the 6AQ5 = EL90 is essentially the same spec as a 6V6, but B7G base. Even same heater current of 450mA yet allegedly 4.5W. I had one German AM/FM set with the EL90 and it ran pretty hot!
The 6M6, EL11, EL3, KT61 and EL33 (various bases) are all similar to each other, about 4.5W but 900mA heater. Possibly due to size you can run a bit more power than the EL90/6V6.
The EL41 (Rimlock) and EL80 (Noval) are roughly similar to each other and 710mA heater, but about 3.9W
The EL42 (Rimlock) and EL95 (Noval) are roughly similar to each other and lower power, only 200mA heater, so about 2W
Any of these will work in a triode circuit with g2 to anode. Check bias for the HT volts on g2. I think all are really Beam tetrodes, so the "plates" are tied to cathode.
