What we have here is the popular amateur Radio which was No.1 in it's Day. If you had this you had the best. It covers 160 to 10 meters in 8 different bands. It is double conversion crystal controlled front end. It has separate detectors for double or single sideband signals. Types of reception are AM CW SSB MCW. This unit has the Mechanical Filter. It has 22 tubes including rectifier and voltage regulator tubes. The Radio is in what I call in good condition. The top of the cabinet shows some light scrub marks. Other than that it looks good for it's age. I am selling it due to health problems. It is serial No 4685. It works well on all Bands.
