In Reply to: Mc C-28 and MC2100 -Sorry for the long response posted by Brian Levy on May 12, 2007 at 07:01:40:
I picked up a C28 and an MR78 some months ago and went through the C28 replacing caps in the line section as well as the power supply. In the case of the line stage, I replaced both channel's caps starting at the input end. For each stage, I then buttoned it up and put into the regular listening system here in the Romper Room (aka: garage). As I worked my way down the audio chain, the sound stage got bigger and the dynamics and authority improved. Using Solen and Auricaps for the most part, the old bird now sings quite nicely. In the end, I did the phono section this way, too, with the same results. Took a lot of work but I can confirm that those caps, now getting into the late years of their 3rd decade, do indeed need attention.BTW, I also redid a local friend's C28 and it responded in the same way.
Cheers,

I wish I knew how to do those things myself. I doubt if i can justify having someone like Audio Classics do it for me....the cost would go beyond the value of the piece, or at least it's value to me. Hopefully I have something that my technician here in Syracuse will barter his time for. The parts will cost peanuts. Maybe with some luck, it won't need anything at all...but we all know there's things to be done, even if they are not necessarily needed at this point.

talk to Terry DeWick in Tennessee. He's been most helpful in the past and many others have used his expertise as well.I'm fortunate to have done my share of 'bench time' at a stereo shop back in the 70s while in engineering school. Turns out to have made for a great hobby over the years once I went to work for computer companies to pay the bills....
Cheers,

Thanks David for the link to Terrys' site. I'm quite undecided what to do with the C29....which is not an unusual state for me to be in. I've got two fellas interested in the pre already. Like my Dahlquist DQ10s that were recently fixed, (then sold) I'd like to hear what the C29 is like before I decide to let it go. I could use another pre, but I was hoping that I'd pick up on a tube based one. Not being familiar with the C29, I'm not sure if I'd like it or not....though I can't imagine myself disliking it. I always find myself in these stupid dilemmas...almost as difficult for me as deciding if I want margarine or butter....lol. Take care.

All of that last post was supposed to say C28. Where the 29 came from is beyond me. The weekend is not even over and my brain is fried. Time for a Dogfish Head 90 minute. Who says you need to wait till noon?

My suggestion would be to hook it up and run it for a time. 1st impressions should be discounted - good or bad. If underwhelming, have your local tech check it out and document what needs to be done. As an alternative, ship it to Mc; their repair department prices are more reasonable than you'd think. The 29 is a rather good preamp and as it moves a bit away from the tube voicing of the earlier Mc preamps is more in line with today's expectations. Also having a lower noise threshold over a stock 28, it overcame 1 of the more legit complaints about the 28. The 28 with a little work can still be with the best of them today but the 29 corrected some of the 28s design and production engineering issues. It's only area where the 28 is better out of the box is the phono preamp. I could have lived as easily with a C29/MC2205 combo that replaced the C28/MC2105 pairing. The 29 is young enough where the caps may still be good though it is in the age range where they should be looked at.
