I drove a pair of MMGs and 12's with a early 90's Marantz stereo power amplifier that sure as hell wasn't 2 ohm stable (I learned this later when using this amp to learn how to do load testing). It was actually a sweet setup, and I realized at some point that I still had that amp laying and tried using it to power a Stax transformer and it worked beautifully.
I wish I could find the post here... anyways, I was shocked to see the cases myself. To ward of the inevitable question of cost, I don't remember, but contact the seller on that page. The Woo cases are pretty much top notch in my book, very well built.
I'm not sure who questioned this, but look at this for sale ad:
diyAudio Forums - Tube amp case - Page 1
Also, I saw the same chassis for sale in China, but didn't take any pics ...
does anyone happen to know where one can get an official drawing of the Stax plug and socket? Or, if the Amphenol stuff is indeed an exact fit, is there a technical drawing of these part numbers?
I was misquoting Nate slightly, I think he would agree matched tubes are desirable, but hard to match unless you have the exact circuit to match the tubes in...
