The JJ ECC99 (6N6P) valve is a double triode designed for preamp circuits and phase splitter applications. Some practice amps even use them in the output stage. And some hi-fi amps use ECC99s to drive 2A3 and 300B output valves.
We test each valve at real amp voltages on our suite of vintage, modern, and custom-built valve testers, including a digital unit which checks over 20 parameters to ensure maximum quality. You can’t buy a better tested or more reliable valve.
Made by JJ Electronic in Slovakia.
Includes our class-leading 180 day warranty.
