I collect US Amps. The manual you have is from the early 90's. The amps, judging from the boards, are the 1999 version. The board should be the same as the USA-150/150X. The rail voltage on the USA-50HC is +/-15V @ 35A. The "white pages" for that amp say it's 100W/CH @ 4 ohms and the overage factor is 15:1. It has (12) 125W 3MHz bipolar transistors. Doing the math in the US Amps brochures 15V x 1ohm = 15A...15V x 15A = 225W/CH. Bridged is 30V x 1 ohm = 30A...30V x 30A = 900W. Someone correct me if my math or way of thinking is off. US Amps are way underrated. GLWS!

Thanks guys, they've been good to me. Glad to have owned these amps but they have to go, got a AQ120.4 to go active, couldn't resist with the Black Friday deal they had going on.
