neon lamp osc with doorbell keyboard
goes into a 6au6 via depth/drive knob with a neon as a modulator -
inductor on the plate for tone
goes into a second 6au6 via depth/drive knob and neon as modulator
inductor on the plate for tone
6AL7 magic eye on the outputs
each modulator has rate knob and ‘range’ switch – one setting being
a .015 cap across the neons – the other setting being no cap between the neons
some how this works really nicely
you know i couldn’t do it without barbour’s help!!!
