Hi Glen

Thanks for the high voltage warning,  I doubt I will ever be able to summon up the energy to over stress on high very often!

We are considering building a radio transmitter to go with the pedal generator,  just for historical interest of course.  We are still tossing up between vacuum tube and solid state but you never know we might do something one day.

I will take a look at that 5 volt supply regulation, this is a fairly old power supply so maybe the bits are discrete enough to be recognisable.
