Vintage Pioneer RT-909 Reel to Reel Tape Deck Recorder

Pioneer RT-909 Reel to Reel Tape Deck Recorder. I purchased this deck in April of 1979. I've serviced it with regular maintenance over the years (with records) in 1984, 1994, 2010, and 2016). It was standard replacement and maintenance of pinch rollers, belts, demag, head alignment, cleaning, etc. I even have the original owners manual. It is cosmetically perfect, everything is in working order. All meters, buttons, forward, reverse, etc. all operational . I do believe it is time to align the heads and clean as the audio is muffled. It's time to sell as I no longer really use it anymore, and I am pricing it reasonable for a quick sale. If anyone knows this Pioneer legend, it is beautiful, sturdy, and built to last. This also comes with the original Pioneer take up reel. Perfect condition.
