I wonder if a Greenlee chassis/knockout punch would work on Chicom grade stainless steel? I have some step drills somewhere but never figured that they would work on anything harder then mild steel. One thing that you could try, if you need more B+ for the power outputs from the supply with the kit is a full wave voltage doubler, A friend of mine has a 1960s era guitar amp where they did that.
