Need a little help with Original Parasound JC-1 amp(s)

So I have pair on demo from a local shop and it appears that they have had parts replaced throughout the years. In the picture I’m looking for the missing heat sink on the input mosfet and I also wonder if anyone notices anything else out of sorts? Any help would be great!




If you use the high bias setting and are driving your loudspeakers hard, they have a significant thermal load. My brother failed his driving Magnepan 3.6s. I think I would set my bias to low unless I was driving easy loads at normal volume. YMMV.

These are driving a pair of B&W Nautilus 801 and I wouldn't think they are too hard on the amps?

I hope these are about $2k or less. Mismatched will be a tough resale.

How about asking Phil at Parasound to give you some advice?

I have a friend selling a good pair in the Bay area. About $5k as

I recall.

Yeah I said 2k with mismatched parts and the dealer took them back to have them matched up (better). Although I think the rebuilt amp before matching up sounding a little better for some reason. I bet the tech never biased them however since they are running at different temps.
