This is a venerable A77 high speed deck that was used by a recording engineer and was in pretty bad condition. I think it was my first 500 Q-tip deck, meaning I used 500 Q-tips with various solvents to clean from top to bottom. I learned a lot about the construction of these decks, how they really function from the bottom up. I added the stainless steel front plate, it was the last cabinet that the original Revox company had in stock when they were in Nashville. I went there for a tour once back in the '80s. The nice thing about this deck is that it can play NAB and CCIR playback, so the Tape Project tapes can be heard.
