Pioneer RT-1011L 10.5" Reel to Reel Recorder

The RT-1011 was introduced in 1974 and was Pioneer's most affordable open reel-to-reel tape deck. It was a three head/four track deck that could take the larger ten-inch reels. It was equipped with three motors and the reels were belt driven. All Pioneer's open reel decks manufactured between 1973 and 1975 employed synchronous hysteresis motors. The frequency response was 30-20kHz. The RT-1011 can be distinguished from the RT-1020 at a glance because the former used black plastic knobs and toggle switches but the latter used machined aluminum pieces. The RT-1011 remained in production from 1974 to 1978.
I purchased this on eBay, but recently purchased a much more expensive unit to accommodate more functions. The glass window on the right VU meter is cracked, however it doesn't affect it's operation. This recorder is in fine working order without any problems.
