[sdiy] Zeners!

[Julian Bunn]

The Minisonic2 envelope shapers use 5.1V Zeners. I found last night that one
of the Zeners I have used is misbehaving, and I don't have a replacement.

My question for the electronics guys on the list is: if I find two lower
voltage Zeners in my parts box that add to 5.1V can I use them in series
to fake a 5.1V Zener?

For the interested, the circuit of the Envelope Shaper is at:
