Medium-Mu twin triode driver tube. 3.5 watts dissipation per plate.
Dissimilar twin triode preamplifier tube used in vintage Ampeg amplifiers. This tube is 1/2 12AX7 and 1/2 12AU7.
Triode-pentode used in low power hi-fi amplifiers.
ECC802S is a long plated 12AU7 medium gain pre-amplifying double triode. Long plate provides a very rich and full sound from the deep bass to the high end. All JJ gold preamp tubes are selected within a close tolerance and handtested for best sound and quality. Furthermore all pins are gold plated to achieve best electrical contact. Files:
COMBINATED DOUBLE TRIODE ECC832 is 12DW7 pre-amplifying double triode. It combines 12AX7 and 12AU7, where the 12AX7 is used as 1st stage and the 12AU7 as 2nd stage. Files:
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...).
