Vacuum Tube - ECC99, JJ Electronics
The JJ Electronic ECC99 is a noval based dual triode. This tube features a rugged construction and is also available with gold pins. The ECC99 is typically used as a driver for power triodes in 2A3 and 300B amplifiers but can also be used as a power tube in small amps and headphone amps. This tube can also be a functional replacement for 5687, E182CC, 6840, and 6BL7 tubes. Note: Sockets on some of these types could have a different set-up.
RoHS Compliant
