RE: Made me look. PIC




Is this The Lost Tube of Lyonesse? I can only compare it to some new production Tung Sol that sound okay on their own but harsh in the treble side by side.

6SN7GTB on the glass, RCA Electron Radio Tube on the base, along with code JBR. The plates look more black than grey.

All I really care about is my 76 line stage makes music with these as output tubes.
