hey... ı'm highschool teacher from turkey. we made a sgtc with my students. now we wanna build a musical sstc. ı found a schematic but ı dont know what should be the capacitors voltages. can anybody please help me. we just want playing music with arcs...the schematics are by daniel eindhoven

 

Hello,

I would take 1.5 to 2 times the applied voltage for the capacitors.
The input voltage of the regulators a voltage of 24 Volts is stated, a 35 - 40 Volts capacitor will do there.
So in the 12 Volts circuits I would use 18 volts, they do not exist so I would use 25 Volts to be safe.
As for the high voltage caps near the bridge, they will get about 380 Volts on them, so I would use 600 volts caps.

THANK YOU SO MUCH
