Microphone Replacement Elements


Genuine Astatic Crystal Element!!!

This is the original Astatic MC-151 element. I am selling a small number of them now. These are authentic MC-151 made by Astatic. Each element is tested before shipping. These fit most bullet style mics including JT-30, T-3, Astatic 200, Shure 707, Shure 520, Turners, American, and similar mics. Some mics require that you trim the rubber gasket or order a specialty gasket from www.harpmicgaskets.com. The back of the element has MC-127 cast into the casing, but Astatic broke the 151 mould so they use the 127 one. There is a paper label with MC-151 on it. No returns after 2 weeks. No returns of soldered elements. I will issue credit only, up to 14 days after purchase if returned element has not been soldered.

Switchcraft 1/4-inch deep panel jack

I use these instead of the Amphenol type connectors. It saves money because you don't need an adapter. Just use a standard guitar plug. It is convenient and using an angled guitar plug makes the mic very streamlined. Just make sure that there is room for it. There should be 2 inches of clear space inside the mic, but the end tab can be bent saving 1/4 inch. If the body angles in, the jack may hit the element. Measure carefully.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into JT30.com in the late 1990s. I accumulated more stuff than I remember. This is some of it.
