McIntosh MR78 upgrades?


I have an MR78 that's working well. 

I can bring it to Audio Classics, and for about a grand, get the power supply and audio section upgraded, and the tuner will be aligned. 

There's another shop, maybe 2 hrs from Audio Classics that does a power supply upgrade for $250, plus an alignment would be billed based on actual time on the bench. So let's say $350-$400. 

Is the audio section upgrade worth $600? Would be most interested to hear from people with Mac tuners that have had them modernized.

I picked up my MR71 for peanuts in the early nineties and cosmetically it happened to be excellent. The electronics were not good. I had the Modaferri mod done with the alignment, and it sounded great after that. Later, I sent it to Sam Kim in Montreal, and he worked his magic on it. After that, I no longer craved for the coveted Marantz 10b.

A few more thoughts about this. Does the tuner equal my vinyl front end? No way. And, I do have concerns that FM may be on its way out. Plus, I moved into a new home, and now need to do the roof antenna reinstallation. Right now, my tuner sits on my rack looking pretty, while I'm trying to figure out how to fund other needed system improvements.

Still, I'm driven to get this all done, because that's what it's about for me. So, yes, the expense was worth the results.

Cerrot - I read a rumor, and I think it was here on Audiogon, that one of the Scandinavian countries has eliminated FM altogether?

I do get the public radio stations, which is what I listen to. So, jazz, classical, and alternative. I really don't care for the rest. Even, my daughters stopped listening to "their" music stations, as the music has become shallow in mind and body in their opinions. I'm digressing.

Many of the antenna manufacturers are no more, or they just manufacture what's popular today. I own an SE Engineering antenna (no more), but I'm in the hunt for an old classic Channel Master or equivalent.

l wonder, if by the time I get my act together with roof/rotor/antenna, will there be a signal!!!? - LOL

zavato - I uploaded Richard's test results sheet after his modification of my MR71 if you're interested. It's temporarily added to my system's pictures. I'm sure their are many guys here, and probably yourself as well, who can analyze those results. I thought this might be helpful for you to determine what to expect from the mod.

I found the MR71 on a heap of discarded gear at a used audio joint. I'm not sure if it even tested before the mod.

tablejockey,

The cabinet was made by High Quality Reproduction Cabinets who specialize in the classics. They offer almost any veneer, and I wanted the Birdseye Maple. Extremely happy with their work, and I still have an original Walnut cabinet that I picked up, but it's also a little tired looking.

When I get it hooked up, I will seek some advice about tubes for rolling, because I can't even tell you what's in it now.
Kenny

Right, good point. It would be nice to find a local guy to do realignment, so when a tube needs to be replaced, I'm not shipping the tuner off somewhere.

I'm wondering how these comments are adding up for zavato? It seems that no matter what we have, we keep messing with it ($cha-ching-$cha-ching). - LOL

zevato - IMHO, no matter how much you put into a tuner, it's still a tuner. It will never sound as good as a fine turntable or digital source.
