Not operational yet but getting there. An ATR-102 rebuilt by ATR Services as a rack mount (FOAK for Mike Spitz) with Bottlehead tube repro and Ironbut Dolby processor. The transport has, in addition to the full compliment of 1/2 track heads, a 1/4 track playback head. It has switches to select between the 1/4 and 1/2 playback heads as well as between the stock and the Bottlehead electronics.
Very decent footprint and, to me, looks very nice!
Still have to fill the void between the deck and the stock electronics. Maybe a Dolby A processor? I read somewhere that Charles is working on them
