Tubes for base

Does it like 845s that is a bassy tube. Subs are not heard they are felt if you want bass get an SS amp and lose the imagery the halographic crystaline beauty out of your system or maybe buy an external x-over and bi amp with an old "all class A" none of these plataeu business amps, get a real cooker.If I wanted you to be an AB amp I would have bought one. Why let the manufacturer say when it will be switching over to a/b and not even tell you. Who let them get away with a class A claim not to mention twice the price.
Just don't let anyone go near it . Or for that matter open the top and touch the lethal voltage tranny leads etc.

yep.. It's subering time.

Tubes will never give you what a sub will.

Period.

All your base are belong to us.

If any in your gear are possibly made by Amperex or Tungsol... try those.
