Intro to the Crunchie Boost

I'm going to try to keep a log of the progress of my guitar effects pedal that I am slowly building (very slowly). In theory as a physicist with access to a fully equipped electronics lab it should be easy, however, finding time when I don't have actual work to do is challenging.

Anyway it is going to be a tube overdrive/boost and hence will be named the Crunchie Boost after two rather well known confectionery items. The circuit is based on the Shaka Tube but initially I wanted to run it off the standard Boss 9Vdc power supply used by many pedals. In a brain-dead moment I got it into my head that this would provide me with +9V and -9V which it won't! Hence I'm now pondering the next move - maybe using a simple voltage doubling circuit for the op-amp input stage but this can't be done for the high current tube output section. I'm not sure 9V is enough of a plate voltage for the tube so it's off to the lab for some experimenting...
