ECC83S (12AX7)
Price range: $20.00 through $27.00
The JJ ECC83S is a High quality, low noise replacement for any 12AX7 type tube. These are available graded for High Gain and also available with current Balanced triodes for phase inverter use, and Balanced-and-Matched in pairs or multiples.
The JJ ECC83S utilizes a historically recognizable short plate design and spiral filament. This contributes to the tubes inherently low noise flow and resistance to mechanical noise and microphonics. This makes them ideal for combo applications and high gain stages.
Tonally these tubes have a very even voice with a dense harmonic structure when overdriven. Compared to other 12AX7 types this gives them a warmer and thicker tone. This also makes them very versatile and a great overall platform. If you’re looking for a neutral voicing with tight dynamics this is where you should be.
All our preamp tubes are stringently tested for noise and microphonics using Amplitrex testers driving an external amp. There is no extra charge for low noise and microphonics testing like with other tube vendors. If a tube does not pass our strict performance criteria it’s tossed or sent back to JJ Electronic for evaluation.
