Big improvement on my Decware SE84UFO
by BobW
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.
