Sorry, I mispronounced...the ziner still uses 12V. Replace the 1k resistor on the negative step with a 2k2 resistor...and replace the SSS code resistor on the positive step with a 33k resistor. The C33N can be used with values ​​ranging from 22n to 33n. Good luck with your work. Happy learning. I hope you all gain useful insights and knowledge. We don't seek perfection in our results...but we take the middle ground from our observations.
