Wow thanks! That's super helpful!
How does
THIS diode look? It's low capacitance, 400v, and fast recovery time. But all the capacitance ratings are at like 4v, so idk.
Also, which values do you think I'll have to tweak? All of them lol? And lastly, would wire wound resistors work in a pinch? That's about all I have on hand, if they'll work for testing, I'll order carbon later once I have the values picked.
