ECC99 Gold Pin Balanced

Product Details

JJ ECC99 Gold Pin with fully Balanced Triodes. We recommend these for long tail phase inverter stages which are common in a lot of push pull circuits, or anywhere that a tube with symmetrical sections is desired.

The JJ ECC99 is a high performance, proprietary driver tube

All Gold Pin tubes feature internal components that have been selected off the assembly line and treated differently during the final construction process.

HIFI users can expect increased bandwidth and a smoother presentation with the Gold Pin tubes.

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 gold pin variants are very lush and open sounding. Ideal where smooth clipping and an increased frequency response is desired.

We recommend these for long tail phase inverter stages or anywhere that symmetrical performance between triodes is sought. It also gives you the plate current and transconductance spec for each triode which is nice if you're trying to keep records or maintain exact consistency from tube to tube. If you need multiple matched tubes please see our "Balanced and Matched" option.
