Studer A807 Old Stock head block, w/1/2 track and 1/4 track playback heads

We are one of the only facilities in the Pacific NorthWest that buys, sells and restores reel to reel tape decks. We have over 35 years experience working on these units, and have the tools and test equipment to properly align and bring these decks to life.
We use MRL calibration tapes, and are dealers for ATR tape. We work on everything from mono tube machines to 2" 24 track studio decks.
We stock many types of ATR tape from 7" reels to 2", in several formulations. We have about 150 decks in stock at all times.

We are going through more of our 'Texas barn find' (see our website for details, under the 'news' section), and uncovered two new old stock Studer head blocks! (see our other listings for the other one).

This is a 0 hour new old stock set of heads and factory aligned head block that fits the Studer A807 reel to reel decks (see pix for the head block connector). These are 1/2 track heads, the standard configuration of A807 decks, however it has a 4th 4 track (1/4 track) playback head mounted to the far right. All head wires run to the multipin subD connector, so we're assuming that the switching between the heads was done on the deck? We haven't seen this configuration before, so we're at a bit of a loss (if you know, please message us, and we'll update the ad!)
There were 4 channel/4 track Studer A807s made as well, however we have yet to see one here in our shop.
We haven't run this head block at all, however we did check for continuity of all 10 windings to make sure they didn't somehow open up over the last 30 years, and all measure just fine.
The pix will tell you a lot more about these heads than we can post here. Super hard to find though, as most of you already know. We've provided shots of the head part numbers for the 1/2 track head, however the sticker has fallen off, and wasn't in the box for the 4 track head.

Free USPS air shipping included in the US, and free shipping in Canada as well via Canada Post.
