Unit is made by audio acoustics, looks to be serial number aa1101, maybe the first unit they made? It came from a 3 track ampex 351, uses beyer peanuts for the sel sync matching transformers, probably roughly 600:50k or close. No other info is known, it’s a pretty rare piece though. It came from a working machine but no warranty is given, sold as is. Engraved in the back is what looks to say p or d porter, perhaps original owner or tech?
