ECC99 Balanced and Matched

Product Details

JJ ECC99 with fully Balanced Triodes. If you need pairs or multiples of this tube matched to each other use this option. These tubes have symmetrical performance between triodes and are ideal where total consistency and repeatability from tube to tube is desired.

The JJ ECC99 is a high performance, proprietary driver tube.

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. Additionally the tubes undergo a battery of tests for basic performance characteristics and faults such as: Emissions, Transconductance, H-K and Grid leakage, etc...

Further, all of our ECC99's undergo a lengthened test duration to insure stability and accurate test results (as is necessary with all high current pre's).

If a tube does not pass our strict performance criteria it's tossed or sent back to JJ Electronic for evaluation.

The JJ ECC99 is a proprietary driver tube designed for Hi-Fi use and used in JJ's own stereo amp applications. It's similar to a 12BH7A (same pin out: 9A) but with increased plate current and higher limiting values.

The Balanced and Matched selection allows you to order multiple balanced tubes that also match each other. 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).
