mark1101 Posted March 7, 2019 Share Posted March 7, 2019 Mcintosh MC-2100 #1 used daily in my Jub setup as a 210 wpc monoblock along with its sister which is also for sale (#2) in a separate ad. Updated by John Warren of North Reading Engineering. Complete output transistor set, power supply replacement, full audio path, gold RCA jacks and power cord. John's website. http://www.northreadingeng.com/ Unit is in great condition for its age. All lettering intact. Has some minor scratches. CLEAN sound. No buzz or hum. Works perfectly. Sounds excellent with Klipsch speakers. Only selling because I replaced with an MC-402. Moving up to more modern Macs. I do not have the original boxes but will ship double boxed in substantial packaging. $1650 + shipping. Quote Link to comment Share on other sites More sharing options...
jwc Posted March 7, 2019 Share Posted March 7, 2019 The 2100's and 250's are my favorite vintage amps. They absolutely sing on la scalas John Warren does over the top refurbs on these units. Quote Link to comment Share on other sites More sharing options...
Audible Nectar Posted March 7, 2019 Share Posted March 7, 2019 I need to file the John Warren name away. I have 2 minty 250s (and will source an MC50 for the fifth channel) that deserve the treatment and will be moved into my home theater. One's got a "hum" and I want to have them all "identically prepared". These are wonderful amps for Heritage. Quote Link to comment Share on other sites More sharing options...

I use an MC 275 on a pair of LS2s, and I was actually thinking of doing something similar. Maybe moving up to a MC 462. I'm not sure yet, what do you think of your move?

mark1101 Posted March 9, 2019 Author Share Posted March 9, 2019 Just to be clear this is a 105 wpc stereo amp that is bridgeable. So you can use in stereo at 105 wpc or as a 210 wpc monoblock unit. Quote Link to comment Share on other sites More sharing options...
mark1101 Posted March 27, 2019 Author Share Posted March 27, 2019 Lowered the prices of both units. Quote Link to comment Share on other sites More sharing options...
