 6GH8A to 7199 Tube Socket Adapter Single 6GH8A to 7199 tube socket adapter. Simply plug these adapters into a socket that is pined-out for a 7199 tube and insert a 6GH8A tube into the adapter. This is intended to make an easy transition to the inexpensive 6GH8A tube as a direct plug-in adapter to replace the now expensive and hard to find 7199 tube. This will work for any tube amp that uses the 7199 tube. Same width dimensions as the tube, so they fit in shielded sockets nicely. |
