I replaced a few of the small electrolytics with better tantilums, some of the cheaper coupling capacitors with a better grade and increased the power value of some of the resistors. I wanted to beef up the entire supply, but there is no room in the enclosure. On the bench I found the poorly designed supply. Same thing when driven to any decent level. So I tried the amp on some Apogee ribbon speakers. The first thing I found when I started to use my amp was it would shut down on my Altec-Lansing 1204Bs I had on my main stereo. The original design used cheap under sized filter capacitors. The other reason this amp gets a 4 is the cheap power supply design. Ok, I will stop my anti-not made in the USA or Europe tirade. Even Crown and many other once fine products are made cheaply in China and sold at very inflated prices. Now would I consider any high priced China anything. For what these amps cost new and all the raves about Bob Carver I would never had bought a new one. I rated the amp a 4 only because it is made in China. Mine has done a great job ever since I picked one up used in the early 90s. CARVER CM-1040 INTEGRATED Amplifier Service Manual ~ Bob Carver - $32.53.
