Done a bit of reading on the subject. A lot of the hits in google were from yonks ago so thought i'd check what the meta is these days. I have a 2021 dsl20hr, which at 20 watts doesn't really push the el34 tube, am i right in that conclusion? So given the 6v6 is lower power, would it give me more of the power tube working harder effect at lower volumes? From what i have read I will state i understand a lot of the sound of this kind of amp comes from the pre amp. So, as i have a matched pair of jj 6v6's i was wondering if they can be used with this amp without stressing or damaging components. I have also read that to do so i would need to use the speaker out that is half the actual speaker load. I.e. 16ohm speaker plugged into 8ohm socket. I understand also the sound of the tube is different, less lows, not as tight, a different midrange emphasis and highs are smoother is what i have read.
