In Reply to: Sperry Microline 12BH7's? posted by BrianM23@msn.com on June 10, 2002 at 18:27:12:
Brian,Is the "12BH7" in the typical octagon on the upper vertical suface? Is there little itty-bitty dots around the printing?
Vertically placed numbers or letters?
More than likely, an RCA, GE, or Sylvania made tube. They are all pretty decent tubes.
