Hey all,

I just wanted to see if anyone had any power tube suggestions for a mark iv. Mine still work but they’re getting up there in age. Thanks all.
 
My current Mark IV came with Mesa STR 430s. I went ahead and bought 440s since I was using them on my previous Mark IV. I prefer the 430s that came with it a lot more. The amp has more punch, warmth, and bigger low end.
 
i remember really liking those small bottle TADs in one of my mark IVa's back in the day. i'm in the market for new power tubes in mine current IVa, so i'm curious what everyone else says as well.
 
I've got a quad of these in mine. They're cheap enough and take the abuse I give them very well.
