Yeasss, mon! One of the 12ax7s tested bad (not shorted, but BAD on the cathode emissions scale). Any reason why this would draw a lot of current?

And the recto tube (Vintage Mullard 5AR4!) growls like an angry dog, so I have left it out. Bad dog!

Amp works!

PLUS! With serendipity! Client asks if I have a spare head cabinet to put it in (because it currently has none). Why, yes! The Dual Showman I bought from Morgan arrived on Monday! Perfect size, just needs new holes for the mounting screws. Love it when vectors meet.
