9V Zener Diode sub for Prince Albert OD

[Plaidesaurus]

I'm out of 9V diodes but have 12Vs on hand. Can I use a 12V as a sub for the Prince Albert OD?

I don’t have the schematic - maybe @Robert can swing by here? I would be reluctant to sub 12v - pretty sure they’re using zeners to maintain consistent voltage to the gates of the 2n7000s but I could def be wrong.

Gotcha. I just placed a Tayda order and added the 9V diodes. Thanks for the input.
