ECC83S Balanced & Matched
Product Details
JJ ECC83S with fully balanced sections. If you need pairs or multiples of this tube matched to each other use this option. The JJ ECC83S is a high quality, low noise replacement for any 12AX7 type tube. These tubes have a warm and even tone with tight lows and quick dynamics. The Balanced and Matched selection gives symmetrical performance between triodes and from tube to tube. This is ideal where total consistency and repeat-ability from tube to tube is desired. 
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.
The Balanced and Matched selection allows you to order multiple balanced tubes that also match each other to make matched sets of tubes. This is ideal where total symmetry and consistency is desired. This is most commonly requested for Audio applications where parallel signal paths exist (such as a stereo pre amp or drivers in a stereo power amp). 

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.
