Hola friends from southern AZ, I just picked this bad boy up yesterday, I heard it playing some awesome Infinity RS 4.5, some vintage JBL's from 1970. John coltrane blew me away, so sweet. It's old but, it really held up to the Jeff Rowland ($15,000) 500w beast, I have to upgrade my electrics to 220amp before I use it with the summits to be safe! Damn if it isn't a piece of art!! http://www.thevintageknob.org/sae-A1001.html, can't stop looking at it just sitting there...
