Any suggestions on the tubes and other accessories to use in my recently acquired 200s/2x15 JBL set-up? What can I truly expect for watts without compromising the sound? Can the 2x15 cab be used with a more powerfull 300 watt head, say the Sunn 300T or Hartke 3500 for live gigs? Just wondering the versatility, or would I be best restricting use to recording and smaller venues?
