I'd question my sanity if I started thinking about a 500 RMS watt

Output transformer looks like it weighs about as much as I do.
There's not nearly enough protection on that monster for my liking,

have a dedicated uP on every output tube monitoring all the
voltages/currents of interest and shutting everything down quickly if
something looked amiss.
Those transformers don't look cheap.
