and we still want to see photos of completed AND WORKING builds.

I also added some sockets for where the diodes are, and rn I have some germanium diodes and 1 led.

i kinda want to put in a switch to switch from germanium to silicon or both silicon and germanium diodes in the middle.

but idk how i would do that, like where would i put the wires and stuff

use an SINGLE POLE on-off-on toggle. replace the diodes on the board now with the leds. wire the Ge diodes back to back, one end to ground. wire the Si diodes back to back, one end to ground. wire switch common to the point on the circuit diagram you are going to show us where the clippers join the signal from the opamp, wire the Si to one side of the switch, the Ge to the other side of the =switch, test, photos, draw circuit, explain the next problem.

no, really, you need to draw a circuit, it is the easiest of switching problems. so us and we'll correct as usual.

instead of that i did this but have ge and si diodes on the circuit board, but theres now a volume loss when i switch to the silicon diodes.




GGBB

A volume loss when switching the clipping to something with a lower clipping threshold (Vf) is normal. The signal can only be as large as the diodes will allow.

this is actually much closer to what i did.

Your silicon mode won't work because you have the 1N34A on the board. You need to have the highest clipping threshold always on, and override them via the switch with lower threshold. You can actually simplify - like this (ignore diode names):

so then itll be full germanium, full silicon, and 1 germanium and 1 silicon? and is the 1 of both mode using the circuits si diodes as well as the ge diode on the switch?
