What sort of sound difference (if it can be quantified) is there between matched and very unmatched tubes?
I have an amp with two KT88’s and one draws about twice the current of the other, currently have the bias pot all the way down (to avoid runaway and I also kinda prefer the sound of cold bias), one drawing 12ma, the other 25mA (485v at plate)
I know I should just buy a new pair of tubes but it does sound good now, and I am dragging my feet dropping £100 on a pair of tubes that was probably £50 a couple years ago.
