[sdiy] Moog 909 power supply component ID question

[Michael Buchstaller]

Hello dear list friends,

for my 904A filter i have also built a clone of the original
909 power supply circuit.
I had tu substitute the germanium output transistors DTG110
with the more readily available ASZ17 - i think this should be
no problem.

But there is a Zener diode D6 whose value i cannot read.
(it may be 1N821, but i am not sure)
Which voltage should it have ?`

Thank you all !
