Manufactured from 1979-1984, this Pioneer RT-909 Reel-to-Reel is in great shape and functions properly. Very Good Vintage Condition. Mechanics Tested (We tested all Buttons & Knobs ie. Fast, Stop, Play, Rec, Monitor) We ran sound through this device to test Sound Pick Up and Monitoring. The Tape Hubs move as they should. Everything has been tested that you can test without the actual Supply Reel and The Take-up Reel.
