recording to Reel to Reel from McIntosh 5300 integrated amp


How would I accomplish this? 

If I'm playing source music (which is either from LP, radio, streaming, etc.) from the amp directly to the Reel to Reel for recording on tape, do I connect RCA cables from the pre-amp's "PREAMP OUTPUT" to the RCA recording inputs on the tape deck?

Apologies if this is basic; never done it and I'm confused because the only plausible "output" from the amp is the "PREAMP OUTPUT" which is confusingly located below the word "INPUTS" on the back of the unit. 

Thanks.

You seem to need the amp to act as a DAC.  
Not gonna happen.
It’s a Mac.
but I think there's a DAC in the amp. I read that from Mac. Maybe I misunderstand your note. anyway, thank you.  
All you need is wires with connectors to connect the things you want connected. Sorry but it really is that simple.
