I’ve been thinking on this a bit and looking at some other places that make some modifications to see what they are doing.
I think that removing the 68K Negative Feedback resistor will make it a bit less bright. As I understand it, removing the highs that might cause feedback with a mic are critical.
Here is an interesting read. I’m not sure what I think about the change to the Rectifier Tube without checking the specs though.
