Selling a Macintosh Amplier MC-352


My audiophile husband died last year. Now the audio system he lovingly crafted and tweaked over a number of years is in the hands of a terrible mother who has no idea what to do with it. He'd be horrified, but I just want something simple to use that I can control via my computer. He was an enthusiastic user of Audiogon, so I'm coming to those of you in "The Club" with the hope that you can help me figure out what to keep and what to pass along to someone who will appreciate it better than I can.

My first question is about the amp and preamp. The amp is a Macintosh MC-352. The preamp is a Macintosh C2200 Tube Preamp. (He also has a Macintosh MCD 205 compact disk changer, but my question is really about the amps.)  Sonos tells me that I can plug my turntable WITH a preamp into the Sonos device. (The CAPS are mine, for emphasis.) What I don't understand is whether this means I can use the preamp I have, or if I have to have a turntable that has a built-in preamp (not even sure if there is such a thing). Do I need to keep my preamp?

The second question is about the amp MC-352. I notice that there are none for sale on Audiogone. I don't know if that's because there's no real market for them, or if it's simply rare to see them for sale. I do find a price in the Bluebook for them.  So, is there a market for the MC-352?

Can any of you help?

The biggest single obstacle to selling Mac power amps is the potential shipping damage even if the amp is boxed properly using Mac deigned shipping boxes, the problem is the sheer weight/mass of these little monsters and also the very fragile glass faceplates, I have seen too many shattered faceplates curtesy UPS/FedEx rough handling of these amps..
If it were me I would advertise it as local pick up only, who knows you may be lucky and find someone within reasonable driving distance
Use cargo airlines to ship Mac 
advice buyer to pick up directly from cargo airlines 
that is what I arrange on large and heavy units 
Thank you to all of you who've responded with advice about shipping and the Sonos hook-up. I see why Tom was so appreciative of Audiogon. Its users are a very helpful and kind bunch. It's really a wonderful little (well, perhaps not so little) community.

Tom kept the original boxes for all the equipment. And we had everything crated, anyway, when we moved from Chicago to Palm Springs. The "local pick-up only" advice is good, though I supposed it will limit the pool of buyers. But it's not as if I have to get rid of things right away. They can wait for the right buyer.

And speaking of breakage during shipping. Yes, when we moved, despite them being in original boxes and being crated, the movers actually broke the glass on the front of the preamp. Tom looked into getting it repaired, but I don't remember why that didn't happen. Perhaps because he'd have had to ship it to Macintosh, and there's the Catch-22. Anyway, the preamp has a crack in the glass. Not sure how that affects selling it, though if I can use it for the turntable I won't be selling it anyway. 

Again, many thanks to all of you who've responded. I very much appreciate your kindness and help.
