Neumann U47FET Clone: D-U47 FET Microphone Project PCB Build thread

[globalpurpose]

ignore the ugly transformer board...

Do You have a link or reference for this double mini switch ? very interresting

I recently got AMI's FET 47 transformer and it came with green, red, black, and white wires. Does anyone happen to know the corresponding pads on Dan's pcb? Thank you for any help.

Did you ever figure out the answer to this? I am in same situation. Thanks.

Here is the wire colors for their BV8 Classic...

Thanks so much! I wonder if it works the same on the FET 47 transformer. I hear AMI are not very thoughtful in their coloring of their wires. I do appreciate you helping me at least see another AMI diagram with colors listed. How did you like the sound of your BV8?

Coloring in electronics is arbitrary except for (some) thru hole resistors and some ribbon cables.
There is no convention or standard for transformer leads, that's what data sheets are used for. Download data sheets for each and every part you buy for your builds, and read thru them.

What are your thoughts on the practicality of making a U48, multi-pattern from these PCBs?

Hey!
Could You please tell a source for the 220MOhm (or 200M and 20M) / 1W resistors!
I am located in germany…
Thanks and bye Friedemann
