Price: $99.00
5 matched pair in stock
Item Number: 2004
Manufacturer: Mullard
The 1960s military spec Mullard CV2748 / GZ30 rectifier tubes in this precisely matched pair are 5Z4 equivalents. These slow-rise, indirectly-heated rectifiers should be considered an upgrade for 5Y3 tubes in most circuits, and will drop slightly less voltage.

They have gray plates, bottom O getters, and brown bases. The white print on the glass reads "CV2748 KB/DA" and the Blackburn, UK factory codes are etched in the glass.
Both tubes test as new. They ship in their original boxes.
This tube is sold as a matched pair. Photo is a sample from the lot.
