Ken shot some internal pics of his amp for me which I'm sure he'll share as soon as he sees this.
Also, I've found a second stock Extreme and when I asked the owner if he'd mind taking internal shots so we could see if it was the same primary-as-secondary nonsense he said he couldn't. All of the screws are so tight that the hex heads strip before they move. I offered to open it for him and explained why, he decided to retire the amp instead. What a shitty second half of 2009 SP owners have to look forward to.
