Hello all - I'm looking around for a replacement quad of 6V6s for a 2x5E3 amp and would like any opinions that you all might have of the JJ6V6 vs the new Tung-Sols 6V6s. What I've heard so far: 1) JJs have better upper-mids/highs than the Tung-Sols, (Tung-Sols slightly darker), and 2) The JJ 6V6s are known for their low end. The new Tung-Sols are known for their sweet top end. These descriptions are kind of opposite. Anyone have any experience with these tubes that they can relate? Thank-uns.
