Soyuz SU-017 Tube V2, the flagship large-diaphragm tube condenser, handmade in Tula, Russia. This is the current-production V2, with the upgraded power supply featuring a switchable -20dB pad. Known for its open, graceful top end, warm midrange, and full, balanced low end, the 017 has become a go-to vocal mic for artists including Radiohead, Coldplay, and the Lumineers. Not a clone of any vintage mic, an original Soyuz design with its own character.

Condition: Mint. Minimal use, no cosmetic wear, the polished body and capsule are clean and unmarked. Powers up and performs flawlessly: the tube is quiet and healthy, output is full and detailed with no noise, crackle, or intermittency. The included spare 6ZH1P pentode tube is still factory-wrapped and unused. Sounds exactly as a Soyuz 017 should. Photos accurately represent condition.
