ECC83 MG Balanced and Matched

Product Details

JJ ECC83MG 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 ECC83MG has a fair amount of harmonic density but remains very open sounding whether played clean or overdriven. Tonally it fits nicely between the JJ ECC83S and JJ ECC803S.

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... 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. 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 MG utilizes a medium length ribbed plate design that is much like the old Amperex and Brimar European designs. Sonically it’s nice and thick sounding with a good edge that’s not brittle. It has a bold character with a fair amount of harmonic density but remains very open sounding whether played clean or overdriven. The ECC83MG is a little more polite than the JJ ECC83S which is pretty aggressive. Tonally it fits very nicely right between the JJ ECC83S and JJ ECC803S.

It has plenty of definition even when used in an amp with lots of gain and the microphonics are very low
