Bad Bob Boost...

[Nitro Express]

would love to build one of these...

It's my understanding that the Bad Bob is basicly the same as the Thunderpuss.  It's the AMZ Mosfet booster - http://www.muzique.com/schem/mosfet.htm
As well as the Catalinbread Super Chili Picoso which has a small little tweak to it.

Actually, the BBB is a mini-booster, not a mosfet boost. Both are Orman circuits.

I stand corrected.

PCB available for sale.  The circuit was in the Radio Shack reprint of a National Semiconductor databook from 1973.
