Re: Favorite PI ? Blueberry...most definitely
Hi Steve!  
I know a few examples of fixed bias amps with concertina PI. Here is one of them:  
Similar to this one were most of the early Dynacord amps and some Austrovox amps from the sixties/seventies. I just rebuilt an old Austrovox de luxe 50 (2 x EL34, 2-ch, tremolo), schematics will be up soon.
