something different
« on: Today at 05:17:37 PM »
I bought a tube microphone for experimenting with solid state tube replacement. It has a good size body and removable tube.
So I traced it and found something different the rest of the circuit is standard stuff
I checked my trace a few times
The part identifiers in the sim don't match the PCB markings
I made up the capsule value because I have not measured it yet.
has anyone seen a circuit fragment like this before?
