Awfull Waffle Zener Diode

[BlackLab]

The PedalPCB build doc identify the Zener Diode in the Awfull Waffle as Value “8V2” and under Type “Zener diode 1/2W 9.1V.“ Should it be an 8.2V 1/2W or a 9.1V 1/2W. Appreciate any guidence

8.2v

I’ve been pondering the same situation. CAN a 9.1v be used as a substitute? As in, the circuit needs a minimum of 8.2v. So any thing higher is okay. Or is it a big NO, only 8.2v can be used to avoid catastrophe.

I think the 8.2v is used to keep the IC input "off the rail"
But it's early and I've been wrong once today already.
Also. Take a look at madbean's fritter pcb/doc for his mods
Also, Aion has a good write up of the hotcake which explains what the zener is doing

Tracing Journal: Crowther Hot Cake

Here's an interesting one. The Crowther Hot Cake is one of the original boutique distortion pedals, dating all the way back to 1976. They've been hand-built by Paul Crowther in New Zealand for the…

Thanks for the responses …… noticed on a build kit from “Musikding” they list an 8.2V 1.3W…… how much difference if any does it make to go with a 1.3w instead of a 1/2w

Zener diodes and wattage....

Is there a minimum wattage for +9v pedals? I think this could explain an issue I'm having with my Awful Waffle. The 8.2w zener diode I'm using is rated at 400mw. Is this too low? Can I test a diode while it's soldered in a circuit? (yes, i realize this is troubleshooting sorta)
