I'm the original owner and the Microtel is similar to new with power adaptor and handbook. I purchased this for my recording studio in the 80s to obtain a realtime "telephone" sound in recordings. It's uses are really very unrestricted with great deals of transmitting possibilities!

　　Rugged and portable and I do not even believe they make these any more. Very versatile! $35. Regional choice up in Anaheim
