Carver C-4000

This was basically a newer, updated version of the Phase Linear 4000 preamp that Bob Carver and Bill Skinner designed. From what i can recall, it retained all of the original features of the Phase 4000 and added Carver's Sonic Holography circuit along with a time delay system for the rear speakers, complete with its own built in amplification stage ( 25 wpc ).

I can't remember too much else about this unit, but i'm sure that there is some type of switch to power it up. After all, it had all kinds of switched outlets on the back, so there had to be some way to turn it off & on. Sean

On my Phase Linear 2000 II, the power on/off is at full counterclockwise rotation of the volume knob.

I have a 4000 that I still use. www.circlestereo.com can service and answer questions regarding your piece, I have had them mod my 4000, he used to be a service tech with them back in the day. Hope this helps.

i've seen pictures of this unit. i must say that it sure is a nice looking one to match up with a series 1 400 amp or a 700b amp.
