Heeeeeeeer's Johnny! Sorry, couldn't resist...
Please post an introduction in the Fret Players section too if you can.
I can't even remember what tubes they are - Svetlana I think. They improved the sound a lot. The EH are good tubes too but mine were dead and rattled. Never tried Ruby's.
My Alltone has seen it better days, so I use a 2x12 Avatar cab. I suppose I should replace the speaker in the Hellhound some day. I was thinking about an Eminence Wizard.
I don't know enough about biasing amps to know what you are talking about... but thanks for the info.
