USD $‎49.95
The NOS Winged "C" (SED) 5U4G / 5U3C (5C3S, 5U3S) Grey Plate rectifier tube is an exact Russian equivalent to the common Sovtek 5U4G vacuum tube and is an exceptional value at this price. It is a directly heated full-wave rectifier tube.

Our stock is from various batches, most from the '80's to early '90's. Some are labeled with the Winged "C" logo and some are not. Regardless of label, they are all made by SED.

Replaces any 5U4 tube type.

Big improvement on my Decware SE84UFO


I swapped the Valve Art 274B rectifier with a NOS SED Winged-C 5U4G , swapped the 6N1P with a Russian 6N2P, swapped the SV83 tubes with thetubestore Preferred Series 7189 tubes - now the amp sounds 1000% better to me. I was a little disappointed with the DecWare SE84UFO sound out of the box, but now after tube rolling it sounds natural and detailed to me.
