Since my memory was dimmed by the Bali Hi, I don't remember what amp Berry brought, I vaguely remember it to be a Sunn rig.
There is a pic in that EBAY listing of Lamar Williams playing that head thru a couple of crazy rare SUNN Orion Series 2x15 cabs. I have a pic of Berry using them as well.
That was the SUNN cabs with the b&w striped grills that The Who used to record the Magic Bus album....but they blew up a truckload of them during the sessions....SUNN realized there was a design flaw and shit-canned the entire Orion Series and recalled whatever was out in stores.
VERY rare. I collected SUNN for ages and owned a mountain of SUNN gear and actually never saw ANY of the large Orion cabs in person. I had one Orion combo amp.
The series was designed sort of like early Acoustic amps....pre-amp contro heads with the power amp in the speaker bottoms. When The Who blew up tons of them, SUNN realized that when the power amp got hot when cranked, vibrations in the speaker cab caused componant int eh solid state amp to fail in virtually ALL the amps.
