6BH8 Vacuum Tube

The Versatile Triode-Pentode for Radio and Audio Applications

The 6BH8 is a combined triode-pentode vacuum tube that earned its place in countless radio receivers and audio circuits throughout the 1950s and 1960s. Its dual-function design — a triode section and a pentode section sharing a single envelope — made it an efficient choice for designers who needed two stages of amplification in one package. Whether you're restoring a vintage radio that originally used this tube, maintaining a piece of vintage test equipment, or building a new circuit around proven technology, the 6BH8 delivers reliable, consistent performance that modern solid-state components simply cannot replicate.

Tested and Ready to Install

Every 6BH8 we sell is individually inspected before it ships — checked for emission, shorts, and noise. You receive a tube that is ready to drop into your circuit and perform, not one that requires a trip to the tube tester first. The 9-pin noval base is the standard miniature format used across a wide range of vintage equipment, making this a straightforward drop-in replacement for any set that originally called for a 6BH8. One tube per order. Inquire about specific brands at a 20% premium, or ask about tested used tubes for a 20% discount.

For Restorers and Builders Who Demand the Real Thing

There is no substitute for the correct tube in a vintage radio restoration. The 6BH8's triode-pentode configuration was chosen by engineers for specific circuit reasons — and replacing it with a workaround compromises the design intent. Stock your bench with the right part and restore your equipment to the performance standard it was built to achieve.
