I'm putting a hold on this and closing the thread- I have come into finding a need for this auld booger. And it's not like you guys are cueing up around the block anyway! Lol... so thread is closed for now... Upgraded model, from the original SM-400, by SWR. In great shape, you know this amp... 400w @ 8 ohms, 550w @ 4 ohms. Stereo @ 250w per side, 4 ohms... Specs are here. Another SWR steal-deal @ $300+ shipping from RI, 02917. Pix: The fan... Rack rash: I would've just done a slide show, but I have other pix in the same folder... anyway there she is. Thanks for looking in!
