I may try getting a JLI electret. Do you know what circuit it is replicating? I am curious if anything can be done to improve it, or what it's attempting to clone.
I have no idea on the circuit. I doubt they reverse engineered then simplified the circuit from its Austrian namesake. It's likely something tried, true, and very generic. But the board in the 25mm version does have a transformer on it, so it can't be all bad.
Actually, it's this capsule:It's probably the JLI electret capsule you're refering to?

The added thickness of the green rings made it a royal pain in the ass to get into the head basket. All of the internal plastic that holds the capsule... I ended up designing and 3d printing a whole new one. The capsule needs to go into the head basket at an angle to clear the frame, even after shaving down some of the frame with the Dremmel tool, and the stock piece didn't allow for the twist.

If I were to do this mod again, I would use the this capsule instead:

It looks like the same capsule, but without the plastic decoration glued to the thing (likely is, judging by the numbers and freq. response). I wish I realized this sooner... I'd still need to print the capsule holder, but the capsule would likely fit without the need for the Dremmel tool.
Though I do think it looks pretty sweet when you look through the head basket and see that smooth shiny surface.
