Available for immediate purchase is one (1) WESTINGHOUSE 5V3 NOS/NIB Black Plate rectifier vacuum tube, made in Canada. The box has some shelf/caddy wear.

This tube has been tested on my calibrated TV-7 tube tester with readings of 55/53 where 40/40 is minimum. 

This will be well packed to ensure a safe arrival. 

Shipping cost includes tracking with Canada and USA only, International shipping does not include tracking.

I am happy to combine shipping costs where possible.
