The workshop was in the back. I’d walk through the front door and I seem to remember there was a glass case at the narrow entrance. There was wall shelving there on either side with amps, receivers and speakers. To get to the actual workshop, I had to walk down a narrow hall to the back. I believe there were two rooms, one on either side in the back. One side had the test equipment, the other side was where those large speakers were. They weren’t tall, a bit shorter than Cornwalls, but just as wide and definitely deeper.
I think my last visit was back around 2010 or 2011.
Sorry for taking over the thread. Hopefully the OP responds soon and let’s us know where he lives and hopefully it’s near you so you can get the business.
I see you like GAS equipment! I recently picked up a clean Ampzilla from AKer Rmac with one crackling channel I need to repair.
