Tung-Sol 6CG7 / 6FQ7

• Brand: Tung-Sol
• Type: 6CG7 (electrically equivalent to 6FQ7)
• Origin: Made in USA
• Era: Early–mid 1950s (roughly 1952–1956)

These are true Tung-Sol manufactured tubes, not rebrands — the internal construction and the box style confirm it.

How we can tell the age

🧱 Internal construction

• Gray plates (not black plates)
• Tall, rectangular plate structure
• Mica spacers with scalloped edges
• Very clean, symmetrical assembly — textbook early Tung-Sol build quality

🖋️ Glass markings

• The worn white stencil “6CG7” and “MADE IN U.S.A.”
• The partial internal codes and faded lot markings are consistent with pre-date-code standardization, again pointing to early 1950s.

These are NOT later 1960s types

Just to be clear:

• Not late-production RCA-style 6CG7s
• Not Sylvania-built
• Not Japanese or European rebrands
  These are real-deal American Tung-Sol, from when Tung-Sol was at its peak.

Sonic reputation (why people love these)

Tung-Sol 6CG7s are often described as:

• Open and spacious
• Very linear midrange
• Excellent image focus and depth
• Slightly more “alive” and dimensional than many RCA or GE 6CG7s
