What is the 6360 vacuum tube?

The 6360 is a tetrode vacuum tube designed for push-pull applications. Push-pull beam pentode..

What are the key specifications of the 6360?

Amplification factor μ ≈ 8, transconductance gm ≈ 3.3 mA/V, max plate voltage 300 V, max plate dissipation 7 W, heater 6.3 V / 0.82 A.

Is the 6360 still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the 6360 as Moderate availability. NOS (new-old-stock) examples from RCA, Mullard, Tung-Sol, GE, Sylvania and Telefunken trade among collectors; modern production where it exists comes mostly from JJ Electronic, Electro-Harmonix, Tung-Sol (New Sensor), Genalex, and a handful of small-batch makers.

What does the 6360 sound like?

Push-pull beam pentode.. Sonic character also depends heavily on the circuit operating point, the surrounding tubes in the stage, and the output transformer when present — use the interactive loadline calculator on this page to explore the trade-offs.
