What can i use as a sub for the 1n419's

Would a D9 germanium diode work ok?

First, let me apologize for the typo. The correct diodes are 1N914's, but any garden-variety Si will do. The layout has been updated to correct the mistake.

That being said, I make my layouts as references for my builds. I mod almost every circuit I build, and I document everything to prepare for the inevitable future time when I forget what changes I made. So the layout just shows what I actually built. But obviously you should feel free to modify the circuit to your heart's desire, just as I did.

The clipping switch gives you Si (1N914), Ge (1N34A), or no diode clipping. You can swap the diodes as you please and the circuit will still operate, but the clipping flavor will change. You can replace either set of diodes with your favorite Ge or Si clipping diodes, or you can design your own clipping switch: led's vs. Ge's; 1 Ge and 1 Si antiparallel vs. 1 Si and 1 led antiparallel for two flavors of asymmetric clipping; symmetric vs. asymmetric, etc. It's entirely a question of what suits you best.
