Kit, I have that amp (actually an HD-130) with a single 15" JBL speaker, and it's as rich and warm as can be. I replaced the original Sylvania tubes (not 6L6's, but rather 6CA7's or something like that, equivalent to an EL-34) with Svetlana EL-34's and am VERY happy with the result.


Definitely re-bias!


You might look at speaker upgrades, as well. Lots of good speakers out there, and in enough different flavors that you can nudge your amp in just about any direction, tonewise.


Good luck!
