Dual Rectifier 4 Tubes vs 2 Tubes

Description

For curious Dual Rec owners, 100w vs 50w: four tubes vs pulling two tubes, silicon rectifier TL;DR 50w has less bass and more mid bark. Pic is of a match EQ set to 200% match, to visually highlight the tonal change To me it feels less compressed, but since it's louder when normalized to peak, it's probably technically more compressed. I think the feeling comes from the upper mid boost emphasizing pick attack. Whatever's causing it, it feels more fun and alive to me, even when you take a minute to level-match Methodology: Didn't touch any knobs between captures, just pulled two tubes (and one rectifier - not applicable in this scenario), and switched the output jack to compensate for the change in resistance. Normalized to peak—as expected, the 50w take was boosted roughly 3dB by normalizing
