Hook Up Revox Reel-to-Reel to Tube Preamp

Are you planning to record with it or simply to play back existing tapes? If for
playback, simply connect the Revox outputs to any line-level inputs on the
preamp (you'll need a XLR-to-RCA adapter at the Revox end). Recording will
likely be more difficult. For starters, how many line outputs do you have on the
tube preamp? I have two open reel decks, one of them a Revox A77, by the way.

And be prepared to find an open reel tech who is experienced with Revox decks.
The B77s are decades old and will undoubtedly need service and adjustment, no
matter what the seller says. My A77, for example, came with what my tech
called "firecracer capacititors," one of which exploded shortly after I
got it.

AFTERTHOUGHT: Frankly, if you're really considering an open reel deck, I
wouldn't pair it with a preamp that omits tape inputs and outputs.

You can hook up to an input and an extra main out if you have one. Just don't overload the input (too high a record level) when recording.

Thanks for the responses. I need to rethink this endeavor since it sounds more complicated than originally envisioned. I wanted to record and playback but since the tube preamp only has four source inputs and one main output, it seems like this activity won't fly.

dump the preamp! i can't live without a tape loop. that's the whole purpose of having a preamp in the 1st place. NMHO!

I want to correct an error in my post. The Revox tape decks have RCA connections, not XLR (I was confusing it with my Otari deck).
