Many thanks for the timely posting - one of my business partners
requested that information to repair an old 4000, and I didn't have
them.

Keep in mind that there are a couple of variations on the front end
circuit, but if you find that yours is different, it is likely the one
where the driver devices are a butt-load of to-92 devices in parallel.

:cool:

Thanks for the heads up. I can't wait for it to arrive and I can dig in!

I finally got around to digging into my Stasis II and its in pretty bad shape. driver board devices and resistors popped like popcorn and there are several output devices dead per channel. The damage is bad enough to make me question rebuilding it. Sure would be a nice chassis to build a 200wpc mosfet amp out of!
