Svetlana Winged C Tubes: The Legendary Russian Vacuum Tubes

Svetlana Winged 'C' Valves

Svetlana Winged C vacuum tubes, these are highly regarded Russian-made audio and guitar amplifier tubes produced by the original Svetlana factory in Saint Petersburg. The "Winged C" logo is actually a stylized Cyrillic letter "С" (which corresponds to the Latin "S"), and it became the identifying mark of the original Svetlana tubes after a trademark dispute.

 

  • Winged C (SED) tubes were manufactured in Saint Petersburg and are generally considered premium tubes for hi-fi and guitar amplifiers.
  • Around 2001, rights to the Svetlana brand name in the U.S. and Canada were acquired by New Sensor. After that, tubes from the original Saint Petersburg factory were sold under the Winged C / SED designation in those markets.
  • The original Saint Petersburg production of Winged C tubes ceased around 2011–2012, making genuine examples increasingly scarce and collectible.
  • Common Winged C models include EL34, 6L6GC, 6550C, and KT88 variants

Because production ended years ago, any "new" Winged C tubes on the market today are typically:

  1. Genuine old stock (NOS or NIB),
  2. Used pulls,
  3. Or occasionally counterfeits, so buying from Hot Rox UK will ensure genuine and tested Winged 'C' NOS Valves
