C29 love...

I love to hear these stories. Have you ever overhauled the 2105 amp? Mine works fine but I've thought about sending it off to Terry nonetheless.
 
The C34 is the model that came after the C33. Very similar but with some video switching control of the outboard MVS3 and one phono in place of two. Later C34s had gold plated RCA jacks.

thanks,

The C34 phono board is basically the same as the one of the C33. The parts for the 2nd phono was not installed and jumpered as tuner input. Attached is a picture of one that I was repairing due to part shorted out.

I found the C33 uses different kind of output transistors and case style for the monitor amp than the later C34. One of the early serial number C34 I have has the same OT as the C33 but my later serial number C34 is different.

I'm glad to see this thread developing right now as a C29 found its way into my main system last night. Chassis is fair but it has a new faceplate. No problems/issues, but it will get a recap before long. I have pictures at home, they'll be posted soon.

Speaking of which.. how about a C29 love app-note in HTML format similar to C34v love? :) :)

Sure, any unit that is 30 years old is due for a freshening up.

This raises an interesting point that is especially relevant for me right now. Is there a particular number of years that trigger the need for a thorough going-over in SS units? My MAC4300 turns 20 this summer. Sounds great, and no noticible problems, but should I be thinking about sending it in for any sort of update? The MC754s that are driven by its pre-amp are of similar vintage but I don't know anything about their service history since I bought them used only a few years ago. Or should I just leave well enough alone until and unless something goes bad?

Thanks.
 
Maybe, maybe not. Your 4300 is a decade newer as are the 754s. You are probably fine for now but nothing lasts forever. When it is time for service the right new parts can bring it back to like new performance .

With the help of this thred I recapped my C29. I also replaced the opamps with the newer low noise versions. I bought this preamp years ago used and I never loved it. The low end would get real bloated at higher volumes. There also seemed to be a bit of channel imbalance. After the recap the amp is sounding great. It really is a night and day difference. All the old caps tested within tolerence so it might be just the opamps that made the difference. Either way it sounds really good now.
