Vacuum Tube - EL84, JJ Electronics
The JJ Electronic EL84 is a solidly built EL84 / 6BQ5 with excellent tonal qualities. JJ’s rugged construction of this tube offers high reliability without any compromise to the sound. This tube has solid lows with warm bright mids and shimmery highs. When saturated the harmonics are rich and dynamic. The JJ EL84 nails the classic sound of this tube. This tube can replace any EL84 or 6BQ5 tube.
Matched versions of this tube use Apex Matching
Choose burned-in tubes for maximum stability and performance.
