Technics RS-1500
and the 1506, 1520, and 1700

From the Technics 1500 Series of reel-to-reel recorders comes the workhorse of a machine that has digitized the majority of the historic reel-to-reel audiotapes heard on SoundTheology.org.

A significant advantage of these recorders is that they can play back at 3.75, 7.5, and 15 ips. They also contain¬†playback heads for both 1/2-track and 1/4-track recorded tapes. And they can run 10.5-inch reels. This means they can play back most reels of 1/4″ audiotape.

Panasonic introduced this series of Technics of recorders in the late 1970s, and built them into the 1980s. There are usually several of these machines available on ebay Рas well as lots of parts.
