The crystal in the microphone stopped working several years ago. I really liked the performance of it, and would really appreciate a suitable replacement for it. Would anybody know where to get an original, or something that would perform like it? Any info is greatly appreciated, so thx in advance.

unsure the word crystal maybe barking up the wrong tree jm + 2u or 2u, had all in the past very old jm+2u i liked, worked very well on ss360\148 cobras not a lot inside the mics work off 7v etc, found the mic cones r the same- as k40,orig s-processors r the same silver eagle sim internal workings they use sim cone for the audio(band width) metal,cup -metalmic lever-special,cone.its not just basic ole aluminium.thats the beauty of it? on a silver eagle you can allter the foil by making holes in the cone to alter the audio band width-silver eagle only.

The original is a piezoelectric high-impedance "ceramic" cartridge. It can die from excess temperatures, humidity, shock, age and any or all of the above.

Mouser electronics http://www.mouser.com has some chinese-made crystal and/or ceramic cartridges. Or used to, at least.

The larger the better for that mike. A larger diaphragm tends to mean more output.
