Brimar 6AL5 / EB91

This Brimar 6AL5 is a high‑quality dual signal diode tube, also known by equivalents EB91 and CV4007 (and in special quality CV4025) for more critical applications. The tube offers two completely independent diode sections isolated by an internal electrostatic shield — ideal for radio and TV signal detection, limiter circuits, and DC restoration.

Encased in a compact all‑glass envelope with a 7‑pin B7G base, it features 6.3 V heater operation (0.3 A) and supports up to 150 V on the anode. With its clean construction and tested condition, this NOS Brimar 6AL5 is perfect for restoring classic electronics or implementing diode circuits with vintage authenticity.
