Raytheon JAN 6X4W Balanced Single NOS Rectifier 6X4 EZ90

This is a balanced single Raytheon JAN 6X4W vacuum tube. This tube has a 7 pin tall glass bottle with Raytheon markings on the tube.  It tests very strong, with greater than NOS readings. This tube has black plates, clear glass, faded orange lettering, and a square top getter. This is an excellent Raytheon JAN 6X4W tube that is highly sought after, act quickly before these sell out!
