[Amps] anyone build an amplifier use 6T51 glass buble?

[MU 4CX250B]

A cool tube, Hsu, kind of a throwback to the 1960s, when homebrewers
were running 3-1000Zs and grounded grid 4-1000As.  This is a BIG old
triode that I bet is a beauty to see lighted up with that nice
tungsten filament and plate glowing orange.
