This is important information and needs to be carved in stone somewhere, just in case our sun goes micronova (again?). You’re doing a service to humanity in these videos, God speed good sir!
Watching this after your one knob fuzz bread board video makes me wonder if I can use some of my own germanium transistors in place of those silicon ones? I have a dozen or so that match the hfe and leakage values shown in this video. there's no bias control on the board tho. I have been swapping out different value resistors on the Q1-2 feedback, the 150k, since I'm already using different Si transistors (i don't have any bc109 so I'm using bc107 and 108) and found I like a 220k but I don't actually know if that's biasing or not lol.
@@oliverlangrall2014 you can absolutely substitute germanium in this circuit, just make sure if it’s pnp to flip the polarity of the electrolytic caps. You can replace the resistors attached to each transistors collector to bias, or replace them with pots. I’ll go over this in a video soon when I do mods to the circuit! Mike

@@SeekerElectricEffects Awesome! I'm gonna have some fun after work today :) I really look forward the video!! Thanks so much!
