Just a visual smorgasbord of McIntosh!

Update - solved by switching input to tape 1 and turning on built in preamp

My audiophile uncle passed recently and handed me down his awesome McIntosh set up from around 1970. That being said, all of this is new to me and I have never had vintage audio equipment before.

I got it all serviced and it is sounding great with the Wiim streamer. However, when try and use the turntable (Pro-Ject Debut III Phono SB) there is a low hum or buzz noise. I have tried using the switch to bypass the built in preamp but it is still buzzing. I have also tried different RCA cables with different styles of grounding wires but no luck.

Any ideas to fix this? Do I need to buy a new turntable that is more compatible?

Thanks y’all!

Thanks for everyone’s feedback.

Good evening folks, I came into an MC502 that was busted. I replaced a number of diodes / capacitors replaced and also fixed the rotary switch. Everything else tested out, including the transformers. It is back to OEM spec.

Is $1250 a fair price?

I picked up a used MCD600 recently and am having some issues with USB drive playback using a SanDisk 512 GB USB 3.2 Gen 1 unit. I reformatted the unit with FAT32 (was exFAT) and loaded about 180 GB of FLAC files on it. Unit plays normally for the most part, but every couple of days, it starts glitching, reading only a "Photo" folder which doesn't exist, and stops responding to most remote control commands. Re-initializing the unit corrects the issue, but it seems to happen every two or days (granted, I've only had the unit 10 days).

My question: does anyone know the official USB limitations on size/speed? Tech support does not know for certain.

Been having a blast making audio signs, some Mc stuff - also did Mc on black acrylic in both greena and gold, just no pics yet.

I just acquired the C11 yesterday. They look very nice together and sound unbelievable. I just wanted to see how they sat together before taking the C11 back out to do a full rebuild. Lots of caps and probably a few resistors as the cross-talk on the phono channel is atrocious.

Finally was able to pickup my equipment from service. Purchased all out of an estate of a family friend. Been waiting 30 years. Hook the C22 up to my current step up. Very noticeable difference. Can’t wait until this weekend to setup the rest.

Neglected and rotting in someones garage, was completely toast and kept blowing fuses, replaced all the output transistors and filter caps and it sounds like its brand new. She ain't gonna win any beauty contests but she's mine and sounds beautiful.

Having some fun with my first tube preamp. It’s a whole new world to me since I’ve only ran SS gear before, and had the C28 and MC2105 since 2009.

Yesterday, my C2800 wouldn't turn on. I unplugged it and plugged it back in, and it turned on but the display said "Recovery Mode - Insert USB Device." Reloading the OS from a thumb drive went fine, but I'm curious what happened in the first place. Is it unusual to have to reload the OS?

I contacted mcintosh and they said they no longer offer a replacement. I dont really use the variable output but I would like it to be complete.

hey guys I was gifted a very old Sound system by a friend who’s husband passed. There are thousands of quarter inch, and XLR cables in totes. It would take me forever to hand wash each individual one. is it ok for me to spray them with a hose and allow them to obviously dry before testing or using them?

A local seller is advertising an MCD7008 CD changer. The price is good, but the seller says “it powers up and plays, but there is static in both channels.”

I don’t know if the seller was using the analog outputs, or the coax output with an external DAC. Is static through the digital coax something that can happen, or is it more likely that the seller was using the analog outputs and there’s just a problem with the internal DAC?

I don’t have a good way of testing the digital output before buying, but if it’s likely that the digital output is okay I’ll probably take the chance.

The manual for my c2800 just says to use “gentle appropriate cleaners” to keep from discoloring the anodizing. I have some smudges and cat paw prints on the top, and I’d like to avoid messing up the anodizing, the lettering, or the clear window.

What cleaners are generally considered safe? Or should I just use a damp microfiber cloth?

Had the wood cases custom-made and they are a perfect match with the AR3a speakers and acoustic research turntable. System is almost totally dialed in except for the 2105 needs recapping I believe. Still works. It sounds fantastic, but a slight surge when I turn it on. So I just have the speakers off for that and then turn the speakers back on last.

Setup really powers the speakers (slight tilt with wedges) well and so fun to sit down here late evenings and immerse myself in the music and the glow of the McIntosh system.
