R.F. DOUBLE TRIODE ECC99 is a 9-pin double triode usually used as a driver for directly heated power triodes (i.e. 300B and 2A3), but in some applications can be used as power tube (headphones amps, small power amps...). All JJ GOLD preamptubes are selected within a close tolerance and handtested for best sound and quality. Furthermore all pins are gold plated to achieve best electrical contact.

Single tube, not matched Standard EL34 made by JJ with a smooth and dizzy sound. Limiting Values:
2 tubes, matched as pair EL34 II has fuller low mids and low end but does not lose headroom in the high end. Stronger than regular JJ EL34 but not as aggressive as the JJ E34L.

2 tubes, matched as pair JJ developed a completly new tube which is compatible with the EL84. The difference lies in the around 25% decreased headroom. This will give you the benefit to get the often desired power amp overdrive at lower volume levels. We recommend this tube for low wattage amps to get a better sound at bedroom levels.
Please check the datasheet!
