Carvin B500 mono block amp for sale. . . I purchased this amp a year ago to use as a back up to my B1500. Ive used it four times. Its a great little amp with the same voicing as the B1500 but with less power. Output is 500 watts at 2ohms, 350 watts at 4 ohms, and 225 watts at 8 ohms. I did use the amp on one outside car show gig with two Schroeder 4 ohm cabinets. No problem running at 2 ohms. This model has been discontinued in favor of the B800. Like the B1500, this amp is built like a tank and is rack mountable (3 spaces). Dimensions are 5 ¼ H x 19 W x 10 D. It weighs 25 pounds. The amp has been in a rack case its entire life and is in mint condition. Price is $350 shipped to lower 48 states. Included is the power cord and manual. Paypal or cashiers check preferred.
