This is a good working STEREO Recordio model R692 tube type reel to reel. I tested it and it is very loud and clear. The transport is kind
noisy at fist because it uses idler wheels, but once it runs for a while it is quieter. It is stereo 1/4 track with built in L & R speakers
If you want a portable machine to listen to tapes at 3 3/34 &  7 1/2 ips without the hassle of hooking up a bunch of wires this is perfect
I checked everything but record and it worked fine even the unique tape counter worked, but due to age is being sold as is.
