G8LSD Valve Collection

The CV4009 is a special quality version of the CV454 and is also known as the 5749 and the 6BA6W. It is a variable μ pentode for use at HF. Most probably as RF amplifiers in radio receivers.

The thin glass tube envelope is 17 mm in diameter and excluding the B7G base pins, is 45 mm long.

Reference: Datasheet.
