All user reviews of 5/5 for the Svetlana 6L6 GC SED

installed for 2 weeks in my GH50L, whose DD showed signs of weakness, sounded a bit dull, winded after three years of service. The pair delivered by Tone Factory is perfectly apairée, and his side I won fermeté.A fact I began to doubt the power of my amp. They are not parmiles cheaper but as they say "the price is forgotten, the quality remains". I recommend a pair for the day my second GH50l sound "out of breath"
