B & K EX-442 Sonata Series Owners Manual

Are there any pages that list the specifications of this amp?

200 WPC at 8 ohms, 350 WPC at 4 ohms. Mosfet output.

Cannot find dampening for the 442, but B&K typically have very good dampening factor.

I’ve had a couple, still have one in a second system, and a real fan of B&K amps. Good tone, somewhat warm, but overly so. For the money, hard to beat. Downside? They no longer exist.

BTW, the schematics are available on-line. Not sure that will help you, but always nice to have if any repair is necessary.
