    Vintage option for MC2105 + C28 . . . ?

    Hello everyone, Background I'm building my first serious system. I've been reading a lot about different speakers, TTs, etc. people have tried with this amp/pre-amp combo, although sadly so few options are available within a four or five hour drive of where I live in Florida. Hurricanes and the...

    Vintage C28 Volume Pot

    Picked up this gently used Alps pot on an auction site--supposedly it was used as a volume control on a C26. Currently it has a 47K resistor from the loudness tap to one end of the wafer--is that the Mc approved resistor for a C28 as well? I went through 2 of the new Canadian Mc pots about a...

    Good price for a C28 preamp and a MC7270 amp?

    I saw a local listing for this pair. Seller says they sound great and have been professionally serviced, I don’t know when. What would you offer for the pair?

    C28 intermittently loses right phono signal

    When playing records in channel 1 or 2 my C28 occasionally loses the right channel sound. I unscrew the lid and lift it and the sound returns. I lower the lid and it will play for a 3-7 minutes and go out again. I lift the lid, lower it and sound returns. Adjusting the cables does not affect...

    Run a subwoofer with a C28?

    Could I use the main center output of my C28 to drive a subwoofer? I'm guessing I'd need to be able to adjust the subwoofer since the C28 won't let me control the output of that particular channel, right?

    C28 + high-power amp = a whole lotta hiss

    Why does my C28 not play nice with contemporary high-powered amps? I connect, say, a 200wpc class-D amp and I get so much hiss I can't listen to music. And I am using shielded RCA cables between the pre and the amp. Then, when I replace the C28 with a Schiit SYS, all the hiss goes away...

    MC2100, MC225, MC240 advice needed

    I became obsessed with higher fidelity sound through Jazz - and I remember hearing for the first time the muted trumpet of Miles Davis on vinyl and being emotionally floored. It was on a really bad system, but that didn't matter - the music went beyond the sound quality and that was my gateway...

    Searching for the Small friction fit "half moon" springs in McIntosh C28 knobs

    I've had to readjust mine twice for the on-off pointer to be correct on two different potentiometers. It's holding okay so far, but I'd like to have a backup IF there's a source for them. TIA...Happy New Year, everybody...

    Another C-28 S.O.S.

    I thought I had this preamp settled down and it was behaving fairly "rehabilitated" until very recently. I'm fairly certain it's the volume pot. I have another one and installed it and it works "kinda sorta". Very odd things happening with the channel balances. I I think I see ground wires...

    Broken wire C28

    I was in the process of replacing a blown lamp near the mode sector switch. Upon lifting the top panel I noticed a white w/blue trace wire not connected. Looks like(assuming) it came off the compensation switch some where. I don't see any broken wires on the terminal strips on the back of the...

    Adding remote control volume to C28

    This may be considered heresy, but here goes. Since I‘ve read so much about sketchy volume controls on the C28, I am taking a set it and forget it approach to it’s use. At the moment I am using a power box to turn all my components on and off and setting my C28 at a max volume setting and...

    C28 lack of stereo separation

    I bought a C28 for a good price, as-is condition knowing it would provide some opportunities to learn how it worked. Surprisingly all things I researched and expected to find are fine. The unit is quiet, no pops or hum, the volume is balanced left to right and I can calibrate the bass boost...

    C28 refurbished and it feels so fine

    I had Mike at Austin Stereo do a full refurbish of my C28. He recapped it, fixed the grounding issues, and got both phono stages working again. Some fresh bulbs and a little elbow grease and it's looking sharp, too. Wow! I had no idea it could sound this good. Considering there are so many...

    McIntosh C28 VS Realistic STA-2300

    First Post...(in this forum) I recently acquired a couple of Vintage McIntosh units at a steal price (since the seller could not confirm functionality). I gambled and looks like it was a good call. I bought an MC2105 power amp and the matching C28 pre-amp. After some cleaning (20 years of dust...

    Houston Area Mcintosh Repairs

    I live in Houston and my Mcintosh C28 is never able to work completely as it should, and I would like to find a qualified electrician to bring it back to a dependable level. The problem is that it will work for a month or so, and something goes wrong, almost like a cycle. I would like to fix it...

    C28 lights and front face plate

    My McIntosh c28 has a couple burned out lights on the face plate. They had been working when I bought the pre from an estate sale, but after detoxing all the pots a couple went out. I heard this is normal? I want to replace the bulbs but I want a little help in doing so because the glass panel...

    right channel buzzzz. MC250 and C28

    I recently bought a MC250 amplifier and C28 pre from an estate sale and it had been working great up to a week ago. The only repairs it needed was some deoxit in the balance pot and volume pot, but with that done I began to hear a buzz coming from the right channel. It is only in the phono 1...

    C28 stereo, right channel not working

    Greetings, I purchased my first vintage hifi setup this weekend and I'm having a few hiccups on my way to having a reliable system. I own a Mcintosh C28 and MC250 which I would like to be able to use everyday. I'm hoping to get to that point on my own with little further investment. My problem...

    MMGs versus Super MMGs

    Hi. I own and really enjoy a set of baby Maggies - MMGs. I'm driving them with a McIntosh MC2105. As others have pointed out, they are really nice and quick for acoustic music in the highs and mids and tight in the bass although they do not often venture too much below 60Hz. In a small room at...
