United Z-225 Rectifier from Radio July 1941, Page 94. 

United Z-225 Rectifier

United Electronics Co. has announced a new mercury-vapor rectifier tube, the Z-225, which occupies only one-half the cubic space of the 866-866A types, and yet has the same voltage and current ratings as the larger tubes.

The Z-225 has a tubular bulb and measures 1¼ inches in diameter and 5½ inches in overall height, including base prongs and plate cap.

Ratings are the same as for the 866-866A.

From Radio, July 1941, Page 94.
