Assuming what you posted is correct
If it is the same process and brand JFET I would like to see the measurement for more gain not just say it has more gain.
EQ changes are easy to do but you need to be aware of what does what
At lower voltage differences cap changes do not matter as much. At the input where there is a greater voltage difference it does.
FWIW in some current test builds I am using tants on purpose at certain places.
Big caps with long leads give you a large loop area and the body of the microphone is not mu metal.
Sometimes you want the high pass switch to work.
How is the AMI transformer "better" than the stock one?
I think people can sometimes forget a bit that people still are trying to make a living... Can’t exactly give away the entire farm... They also still need and have plenty of business for their one-man operation (or close to it), so they have no need to “sell” anyone; with fairy-dust voodoo magic, technical evidence, or before/after sound samples. Another thing people sometimes forget a bit is that there’s tons of art and opinion among all the technical aspects.
Honestly, when it comes to a U87-type, I myself am calling it a day with a Linear Systems LSK170, and extremely-quickly comparing a Samar Audio 9.5:1 to an AMI T13; and maybe a custom Crimson 9.5:1, found slightly better than the AMI in different type of mic.
Certain types and brands of small components in the right application is pretty-well established; not that things can’t always be slightly improved-upon, and there’s still opinion sprinkled in there. Changes in component values and in feedback have long been explored and simply comes down to opinion; and can quickly change depending on the major components chosen.
Will it sound like a genuine vintage or modern U87; or better or worse? I don’t know or care, but it’s still a U87-type mic to me, even if it doesn’t sound anything like a genuine one. If I cared at all, I’d only buy genuine.
