Includes GT-12AX7 tube. The GT6CA7GE is the classic American-style EL34 tube made in the exact likeness of the famed General Electric 6CA7 tube of the 60's. This was the tube we sold to Eddie Van Halen for his Marshalls used on the first two Van Halen albums (often cited for his best tone on record). The Groove Tubes 6CA7GE is a USA-style power pentode tube with similar specifications to the European style EL34 tube. However, the 6CA7 differs in design from the common EL34 types by the use of an active beam-forming electrode similar to that of the 6L6 and 6550. Groove Tubes purchased the actual GE production formulas, along with many of the original General Electric machines and vintage Plate materials via the closing of the GE tube factory several years ago.
