@magic:
i didn't use pots/trimmers..
i used my resistor sub box to try different values, just saves pulling bits on/off the breadboard.
i like to try the unorthadox, ,sims and scopes are fine, but if we all follow the rules it ends up the same...its a great circuit to really mess with...with some good, some bad results, either way its fun experiments
@gordo: yep, electric reflections of war , frank marino, i was brought up on that guys stuff...red hot.
