    I'm working on my friend's AB165, and I'm wondering about what looks like a wacky local NFB between the plates on the 6L6s and the PI Output. Just for a test, I pulled the whole thing out. The amp sounds warmer and fuller, and maybe a bit louder.

    Is there any downside to just leaving it this way?

    I found my answer with a little searching, so in the words of Emily Litella, "never mind".
