I had this post buried in another thread and instead of hijacking that thread away I figured I should repost it here.
I figured the preamp tubes were shaping most of my sound. Mike B at Boogie replace all my tubes (preamp and power) when he recapped it and re built the effects loop, etc.
I'm wondering now about these newer power tubes in my Boogie Mk2b. They are Mesa tubes that say STR 430. Down on the base they say 16 AC YEL. Are these real cold tubes? Is the 16 YEL the bias number?
I'm wondering if I should yank these and go for a warmer Tube. Anyone with any Tube suggestions? I like really like raunchy, warm, black face fender tones...early Pete Townsend, Keith Richards, SRV stuff.
I'm wondering baout getting my amp modded for bias adjustments. Might give me far more options!
