The JJ ECC99 is a double triode that can be used for a driver of power triodes such as 300B - 2A3 - output stage headphone-amplifiers preamplifiers - CD's - power stage little P-P triode amplifiers in class A (10W-4 x ECC99) and parallel voltage power supplies. Can be used instead of 5687 / E182CC / 6840 / 6BL7.
