I bought this amp brand new for $1049.00 back in 1978 when I was 17 years old. I know full retail, but I was a kid and they gave me credit!. What a beauty! My first killer setup. It came with an 18 4 ohm black widow folded horn. I later replaced the horn with a refrigerator sized PV 1820 Front loaded 18 and 2-10s). Also used with a pair of SVT flat 8-10s. 30 + years of experience I say that its not the best sounding amp but a great all around work horse and built like a tank. Took a nose dive from top of a stack in the 80s ( $69 for repair). One repair in 25+ years. Took it on tour around the world with no case! Carried it in a ****bag and yes crashed down the luggage track on every flight! Wow the good old days. I sold this amp after having it for about 25 years and regret it to this day. After using all the fancy stuff and busting my privates with and SVTs I would love to have this amp today (Still looking for one in mint condition). It would take care of 90% of my needs. Its solid at 2 ohms, has a high current output, and great damping factor so it wont clip until driven to the max when miss matched with high powered speakers. 210W @ 4 ohms.
