Can I use my McIntosh MX 113 as a Tuner only

Yes. Use the tape outputs of the 113.

Thanks onemug. Now I gotta review all the conversations about Mac preamps. I'm mostly a 2 channel guy but am thinking of getting something a little more video friendly.

You'll have to spend quite a bit of money to get something video friendly with such a great tuner. I own a MX-115 modded by Richard Modafferi of Audioclassics. I'm located in western Long Island and have no problem picking up stations 75 miles away in NJ, with only a cheap piece of wire as a antenna. With a roof mounted unit, I should be able to pick up Boston stations.

I'm almost tempted to pick up the tuner module for the MX-119 in my HT rig, but with the little FM listening I do, it wouldn't be worth it.

I've been looking at a McIntosh C-39 here and on ebay.

The MX-130 is basically a C39 with a built in tuner. It's remote controlled. You might look for the MX-118 also. Both video friendly.
