I really got into the tube thread and learned a lot last week. So here I come back and I see this kind of crap going on. Sounds like an unscrupulous competitor.
I wanted to add a little bit more to my minimal but slowly growing knowledge (and new fascination) on tubes and ask a simple question. When I asked what PI stands for (in V1 position) I was told it is a phase inverter. What actually does that mean as far as why and what happens to a signal at this point ?
