I couldn't resist the lure of a Soundcraftsmen A100 MOSFET amplifier and P100 preamplifier still NIB. So today I drove over to Anaheim, next to Santa Ana, CA the old home of Soundcraftsmen, to take a look and make the deal.

$234 later I was on my way back home with the boxes in the back of the Sorento. I took them straight home to open them up to see what I'd bought.

No, I didn't want to open them before taking them home, and yes, I have an agreement for a full refund if they don't work.
