The Mullard GZ37 / CV378 is a fantastic rectifier with superb construction and reliability. Made at the Mullard Blackburn plant in the 1960's, they feature a brown base and "O" getter ring. These tubes come in their pristine original British military boxes with corrugated cardboard rolls.
I wish I could leave a review of this tube, unfortunately I had ordered the wrong tube. I needed a GZ34. The folks at TubeDepot were great at handling the return. A beautiful tube!
