Do you have an audio amplifier, a mic input on your sound card or even a pair of headphones around? Try the mic with them. Any audio in the phones is likely very low level but you might hear something in the typical 50-ohm "computer" or "game" headsets around today. Some clip leads and a suitable connector are all you need -- ground and hot lead -- to whatever
If you have an o'scope, it'll show audio too. (Of course you have to make noise near the element ;-) If you hear or see *any* response from the element, it's likely good. Those old crystal and ceramic elements tended to work fine or not at all. Be sure the amp in the base has a good battery in it: 9V IIRC. Ron AC7AC -----Original Message----- Good morning, I have an old D-104 that worked fine when last used (1977) and want to use it with the K2. I know I could replace the element with one from Heil, but I would prefer to keep it as original as possible (it does have the preamp in the G stand base). I will assume the preamp works, and I know the K2 works, but I'm not so sure about the original element in the mic. Does anyone know a way to test the element before wiring it up?
