2A3-40
Price range: $346.00 through $692.00
The JJ 2A3-40 is a modern replacement for all standard 2A3 applications. This tube is built around JJ’s 40 watt mono plate structure and while it meets the classic 250V 2A3 specs, it can produce far more power when run at higher voltages and currents.
These tubes have a velvety character with an extremely even frequency response. This gives them excellent warmth, clarity, and realism.
After manufacturing these tubes go through an extensive stabilization and burn-in process. They’re individually numbered, matched, and shipped with a factory test sheet.
After a 24 hour burn in all power tubes are tested for noise and matched at multiple operating points for plate current (± one milliamp) and transconductance. Please leave us a note in the comments section as to what amp they’re going into and or if you’re looking for a specific grade.
