Comparison: Svetlana KT88 “S” Version vs. Winged C KT88

Origin & Production

Winged C KT88: Made in St. Petersburg, Russia (SED factory, now discontinued). Widely regarded as one of the finest modern KT88s ever produced.
KT88 “S” Version: Current production model made under the Svetlana brand (not in the original SED factory). More readily available and affordable.

Tone

Winged C: Known for its warm, musical character with rich harmonics, smooth top end, and tight but rounded bass. Favoured by audiophiles and boutique amp users.
“S” Version: Slightly more modern voicing with a strong low end and clear highs. Delivers plenty of punch and headroom, well-suited for guitar/bass amps that need power and articulation.
Reliability & Build

Availability

Winged C: Discontinued, rare, and often sold at high prices on the used/collector market.
“S” Version: Current production, widely available as matched pairs or quads at a much more affordable price point.
