I picked one of these up with a "pile" of other stuff sometime back. Photo coming soon. It's a broadcast reel to reel deck, no electronics other than the motor drives on the deck. Two Bodine motors for the reels, one huge motor for the capstan. Built like a rolling mill.

Question ... is this of any value to anyone in your opinions, or should I relegate it to the melting pot of history, or more accurately, the recycler. A shame, but probably too heavy to ship economically.

Thanks for your opinions

What format are the heads - half-track, quarter track stereo? I see it can it do 7 1/2 IPS. What condition are the heads in - worn out?

It looks like there are four heads, that's curious.

Thanks Steve. I'll take some close up photos tomorrow. My initial guess was two track but....... who knows at this point. Might be a clue in how many shielded wires are provided

I'd guess the usual Record, Play, and Erase for broadcast decks. The 4th??? maybe a confidence head?? Maybe one is optomized for higher speed playbvack?

This was a mercy rescue... it was headed for the dumpster. I'm such an easy touch....

We used two Berlants for playing "Sunday programs" (religious and FCC required local issues programs) at the high-energy, top-40 station that I worked at. They were real workhorses. But I remember them as having only three heads. They used the full-track mono format. The Ampex machines in the production studio were also full-track.

There was an early stereo tape format that required two half-track heads. One channel had a head mounted upside down a short distance away from the other channel's head. It was called the "staggered head" format. A short time later, the "stacked head" format was developed which combined the two channels into a single head. This quickly made the staggered head system obsolete.

Maybe your Berlant was set up to play older stereo tapes that required staggered heads and could record and play using the stacked head format, thus the need for four heads. It looks like two of your heads have two channels and two others are single channel, judging by the connecting wires.

Without the matching electronics, I doubt if your deck has much value except as a parts unit.

Close up photos of heads.... appears to be 2-track. And rather well used.

The two on the left appear to be half-track erase heads set up to erase the top track, the bottom track, or both tracks. As mentioned, all of the heads are well-worn. The erase tracks are slightly wider than the record and play head track widths to ensure the entire tracks get erased.

Looks like it could do 1/2 track stereo or mono.

I suppose one could take the transport and make something to rewind or fast forward tape or clean tape before it gets used on a reel to reel player.

I'd love to find someone that wanted this deck ... I saved it from the landfill. (auction, no bidders). ... so now what to do. ??
