Martin: They are not interchangeable. One of my favorite preamp tubes. They are what make a Gibson GA-40 what it is...wonderful. I asked doc the same question, and he said the problem is that because of it's gain structure, which is lower, he couldn't get it to drive a tone stack the way he wanted. A direct swap for the EF-86 is an E80F. It's a little more 12AX7 sounding than the EF86, with less gain and clean headroom to my ears.
