What is the most powerful vacuum tube ever made?
I'm looking into building the most pewerful tube audio amplifier possible. I'll be using 4 tubes in push-pull parallel. (per channel). My goal is at least 5000 watts RMS per channel (if possible). I will likely rewind some pole pigs (power pole transformers) for output transformers, and possibly use one of them in reverse for the power supply transformer, which should supply 3250 to 7500 volts to the plates (or up to 15KV if I use a different pole pig rated for higher primary voltage).
