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!!!
