Thanks Dan. I love restoring old McIntosh stuff like this especially since the MR80 tuner really sounds fantastic. I'm so glad I picked it up.

What's really amazing to me about this particular tuner is the early technology it sports and the number of IC chips they used. It's the first digital display McIntosh tuner and there's 18 or more ICs just for the digital counter and display alone, with 68 ICs in total!

IMHO, if you don't have a descent tuner in your system, you really are missing something.

Nice MR 80. Mine stopped locking onto stereo signals so it is being restored by Mark Wilson of Absolute Sound Labs. I'm looking forward to getting back in the system.

The MR78 is on its way to Audio Classics. They will receive on Thursday. Now the wait that I expect will be rewarded. Wonder what the Modafferi mod will be like.

Mike....I've been pretty busy and haven't been on the site a lot. This is the first I've seen your MR80 with the new glass. It looks great, you did an excellent job. Enjoy....you've got yourself a fine tuner for sure.

Thanks guys. I just got done with a partial recapping on the MR80. I changed out all electrolytic capacitors on the 2 power supply boards, the control logic & tuning board, the digital counter board, and the headphone amp & turn-on delay board. I even found two coveted Blackgate caps in my stash that replace a pair of cheepo caps in the signal path.

I did find a design issue as well. It seems they used a 40 volt filtering cap that's actually running at 43 volts.

Of course, I had a little Murphy's law incident, but thankfully I was able to repair my mistake. It's tedious work and while I think the result are not very noticeable sonically, they should keep the tuner working for the rest of my lifetime.

Young blood here reviving ancient thread...

Just bought a Sansui TU-9900 and pick it up this Thursday. Pretty excited about it! Not sure how it compares to the other tuners mentioned here, but I figure it will be better than the crossley radio I got for 13 bucks that has been hooked up to our living room system, lol.

Figure these things will only appreciate over time, and man we have some great jazz, independent, & public/classical shows broadcasting these days. This will be my first ever dedicated tuner in a hi-fi system.
