Svetlana SV83 Matched Pair

SV83 is an inexpensive but highly linear low power output tube similar to EL84.

SV83 tube has higher conductance than EL84 (15K vs 11K), but the screen grid (g2) of SV83 cannot take as much voltage (200V vs 300V) as EL84. Because of this, SV83 is not a direct replacement for an EL84.

SV83 tube has many fans, and there are great sounding amps such as Decware Zen that are designed with SV83 tubes. SV83 tubes are often used in DIY designs as well.

Svetlana SV83 tube is a Russian 6n15n, also known as 6p15p.

Although SV83 is branded by Svetlana, most of them were made at the Xpo-pul factory in Saratov where the Sovtek tubes are built.

There have been cases where 6p14p (i.e. not 6p15p) was incorrectly labeled as SV83 in the past. Logo size is not an accurate way to distinguish the wrong tubes. The only way to tell is to look for part number 6p15p in Cyrillic on the tube, and if that's missing, to verify with a tube tester.

You will receive only the correct 6n15n version from us, we stock only the correct SV83 tubes.
