The simple P48 works really well with those capsules and the TSB2590. It has a couple internal RF EMI caps that make all the difference.?

?Thanks Jules. Can you suggest a similarly low parts count circuit that I could use with these JLI capsules? The skinny black china electret boards work but for some reason this batch are noisy, not sure if it's my mod transistors or something else, I tried the simplep48 charge amp style with the drain shorted to case as in the last example in the document which worked - I'm yet to try it fully shielded but I suspect I'm going to run into EMI issues with that one.?
