Finally, a new 7868 tube is available! Electro Harmonix has introduced new production of this hard to find tube. The 7868EH is a suitable tube for any guitar or vintage audio amp that requires 7868 tubes.
Note: The Electro Harmonix 7868 tubes have pins that are a slightly larger diameter than USA made 7868 tubes. This will make them a very snug fit, but they will insert into old sockets. Using a gentle rocking motion as you insert them will ease the installation.
