Well, AK'ers, I owe many of you a big round of thanks. I've finished my first complete restoration, it was a SX-450, and most of what I did was a result of you all asking each other questions, answering them, and leaving pointers to more info. You guys rock! Thank you! It sounds terrific (with Polk 5's, Infinity RS-3000's, RS-10's, and JBL L46's) and is plenty loud for a bedroom or a smallish room. BOTL? Not any more, not with quieter semiconductors and resistors, bigger power supply caps, less incandescent lamp drain, a tightened-up phono stage and trimmer pots for adjusting idle. TOTL? No. But MOTL, maybe....

So, I'll need help again, I'm sure, getting this one restored and returned as a surprise to the unsuspecting couple. It'll kick the jacks off the Bose Wave thing they finally settled on....
