U95S

The U95S was marketed as an upgrade of Soundelux’ former flagship tube condenser, the U95. Both were multipattern large-diaphragm tube mics. The U95S introduced a new capsule, a new transformer, and a new tube. The retail price was 80% higher.

The 6072 dual-triode tube of the U95 was replaced in the ‘S’ by a Russian EF86 pentode, sometimes also called a 6267 tube. In the U95S, the tube was wired as a triode, which allowed it to produce very linear output as compared with most triodes. The review mic sent to MIX used a Svetlana 6267/EF86; it has better shielding and linearity than conventional EF86 tubes.
