    McIntosh MX110Z and C20 (later model)

    Hi, I've been wanting to get a tube preamp for quite some time and am now able to go either way between an MX110Z or a c20. Both have been looked over and meets or exceeds original specs. Perhaps what is causing a pause from going with the mx110z is the cosmetics. The gold lettering is...

    Question for rewiring the C20's power cable

    A previous owner replaced the original Belden with a Taiwanese cable that needs to go, too. I've got a 16g Qualtek prepped and ready to go, but the schematic doesn't list which terminal should get the live wire. Is there a preference for which terminals should get the hot and neutral lines...

    A not-so-original V1 McIntosh C20 preamp and the quest for a baseline of "factory spec"

    Well, I got it Friday and spent the weekend cleaning out 50 years or so of crud with isopropyl rubbing alcohol, cotton balls, q-tips and electronics cleaner. Here are two samples of before the scrub down, complete with crusted cables from decades of buildup... And here's what the inside...

    Preamp outlets in vintage equipment or powerstrip?

    Hi! I've got a really nice early model C20 preamp en route, and was wandering if anybody uses the preamp outlets for tuners/amps/phono, or if those outlets are no longer best for use. I'm used to running power strips/conditioners, myself, but if older equipment like my MR67 and restored Garrard...
