And the issue being hashed out for me is why would "a little bird" would wish to cast the 307A in the light of being made up from readily available parts? Of course it is, there's hardly an amp of any kind made that isn't founded in generic parts available online. There's only so exotic one can get without being just plain stupid when it comes to passives. In this case, no effort was made to be particularly exotic in component selection, and the ad copy is unapologetic about that. The goal was to use what sounded good, not what sounded good on paper. My opinion, having heard the amp extensively at CanJam FLA is that Pete succeeded. Just like I thought Craig had done very well with the design of the Balancing Act I heard there too.
