This is my current #1 shell of choice... with a black label Shure CR element from the late 40's. I've had literally dozens of these mics over the years...but Always found the original elements much weaker than the one's I'd found in JT's. They were different, in the sense that the crystal elements in JT's were con-cave...or in other words...the tin foil was shaped like a speaker..and the center connecting pin was short. Whereas with the #200's I'd found...the elements were con-vex. The pin was long and the foil was much higher in the center going to the tip of the pin.
My point is...every element with this con-vex or outward shape sounded very weak..in comparison to any of the "sunk inward" shaped crystals I've found over the years.
Any mic guru's out there care to 'splain this to me?
Thanks ~TinkerMicMan~
