This is another RCA 45-EY-2 record player, also based on the RP-190 record changer mechanism from 1954.
This has a factory option of a three-position switch and an RCA phono jack on the back. The switch redirects the signal to the internal amplifier, an external amplifier, or both.
This restoration works as good if not better than the day is was built. Originally for monophonic 45 RPM records, this unit has been upgraded to a modern stereo ceramic cartridge with diamond needle (bridged for monophonic output). The original cartridge was a crystal device which even if it were in new condition would not effectively play stereo records. It has new rubber throughout and it plays a whole stack of records without a hiccup.
