Description

This listing is for a Zenith 6BA11 Compactron. The 6BA11 has two pentode and a triode in one tube. It was used in many late model televisions, but has recently been discovered by DYI experimenters for audio amplification. This one appears to be NOS, and tests good with no shorts, on a Precision 10-12 tester (with A-15 socket adapter). At this price it’s a good deal. Because, they are not making any more of them!
