Went and picked this sucker up yesterday. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2506577884&category=10171 Turns out three speakers are original, and five are '79 square-mag eminences like in my other cab. The three CTS alnicos are dated '71, so I guess these cabs weren't only made in '69? It's also deeper than my '76 tiltback. More bottom end! Didn't someone say the straightback cabs are thinner? Psycho? ...gotta build a dolly... jazzbasser - what did you do? Just used plywood and casters? Where did you get the feet that go into the cups on the bottom of the cab?
