RCA Chro-Bar Generator WR-502A

RCA Chro-Bar Generator WR-502A - This is an RGB pattern generator used for testing televisions and monitors. This is a true professional instrument, it will generate color bars, dots, crosshatches, vertical lines, horizontal lines, and simple rasters. I've had it since 1970! It is battery powered and I removed the batteries so no corrosion and clean as a whistle on the inside.
