Magnificent musical performance, compact and efficient size, unfailing electronics, stress free mechanics. The RT-707 reflects Pioneer's stay ahead success in Hi-Fi by offering all the things you know you need in an open reel deck, and then some.

Format is quarter inch, 4-track, 2-channel stereo. Performance is 0.05% WRMS wow/flutter, 58dB signal-to-noise, 20 to 28,000Hz frequency response.

And the extras are 2-step Bias, 2-step EQ, ± 6% Pitch Control, Permalloy heads, independent mic/line with mixing, wide-throw VUs, auto reverse / infinite play and auto reversing index, electronic switching (logic circuit), Pause, REC ON/OFF switching for each channel, and lots more.

Great deck!

It's THE quarter track machine to own, along with the 909. The 909 took the quarter track format to the edge of the format's capability. But that difference isn't really worth arguing about. Truthfully, with GOOD tape, the difference between half track and quarter track (from about 1976 or so) forward began to become a bit ephemeral. To my ear (in this order) the RT-2022/44, 1050 (both 2/4 track) 909,707 and then the 1020's. (H/L). I own (or have owned) them all. In general, they're all (even still) undervalued in the marketplace. Unless they're something WRONG with the caps in your machines, you shouldn't experience much of a difference. IF there are leaky/swollen caps, there might be a conversation to be had. In my experience, the mod industry popped up to help repair folks once again peddle their wares. If you have the pocket change to spare (or IF there's a genuine issue) I say go for it. But out of all these machines (that I've owned multiple samples of some six or seven deep) NONE have had capacitor issues. I have had one or two with CSJ's (from having been stored/maintained /transported poorly), but no cap issues. YMMV. Grab 'em and GROWL!!!

Just sold my 8th 707. I have a habit of buying, restoring, and then giving up on them and then buying another one a few months later. A tip (that I was going to follow but avoided by selling): The 707 jumps into a whole new level of performance if you find one with in-good-condition heads and then have the patience (and/or money) to recap it with higher quality caps. A fellow audio geek in my area had one redone (wish I had bought it from him - he later sold it) and the deck was magical - the quality of recordings went up into 2-track league from my PoV. I may do that to the next 707 I buy. There are a boatload of caps there (will upload the list later for others to use here), so tenacity and a healthy Hakko 808 are a must if you are going to Nichicon your 707.

Bought mine off an old repair tech about 20 years ago. Paid less than $150 for it back then. It still works like a dream. Glad I had the opportunity to tell someone besides my wife!

I have owned 2 Rt707s for many years, very solid but was never convinced of the sound. recently I bought a new spool of LPR 35 tape and boy thats what it needed. if you want a good hifi reel to reel this is one of the very best.
