I believe this one may have been a special version offered to Shure executives upon the introduction of the in mid The element in this mic is dated June The tag is navy blue with embossed lettering. I have no idea who the original owner was but I do know who it will be buried with! My personal collection of mics and elements consists of about 30 microphones which are mostly Shure bullets, and some of the various models of the Astatic JT30 which have different model numbers from the early Astatic years. You may be able to see the subtle differences between the various models, or maybe not. I do know that the early models were made in Youngstown Ohio, and the later models were made in Conneaut Ohio. The end of the shells that are more pointed give them the appearance of being slightly shorter, whether they actually are or not. Whatever the case, I prefer the more pointed shells myself. You should be able to notice the bottom part of the shells, the part where the tags are attached, are deeper on the early models than they are on the later models too.

Do you remember the microphone from the 80’s? This new microphone from Superstar is very similar to it but from what I remember this one feels better made! A very unusual mic to look at, but when you get it in your hand it is surprising how comfortable it feels. You hold the mic like a “pistol”, and the PTT is the “trigger” that you press with your forefinger. The mic element is in the top of the mic, so just squeeze the trigger and talk into the top.

Astatic N30 S * * * No. B Crystal microphone. The element has a date (?) stamp “”. The mic itself is probably from one or two years.

Shure introduced the Controlled Reluctance Transducer element in The elements had a unique design that made them immune to temperature and climate conditions. It consisted of a brass disc that was used as the main support for the built in transformer, magnetic assembly, diaphram, armature assembly and cover. It was described by Shure as being a high output microphone with good response, high impedance without the need of a transformer that had its stability assured by unique control of the reluctance of the magnetic system.

Years later they were called Controlled Magnetic Transducers. Shure described them as being pressure operated units using the balanced armature, controlled magnetic principle. The elements have a built in transformer, eliminating the need for an external one.

The d microphone that I bought for the eBay could not have been a better microphone I’ve got real good reports from it it’s very clear I will buy another one if I need one the people that packed the microphone that I actually sold the microphone did an excellent job of packing could not have been better I’m very happy with my purchase I’ll certainly do it again if I need one. Verified purchase: Yes Condition: Pre-owned.

I have used Astatic Mic’s since the early seventy’s. The quality of sound has been one of the best for my hobby. Lately the PPT components have suffered. First, I love the old Art Deco appearance of this microphone. Unfortunately the D’s are quite out of date electronically. Frequently the original Dynamic Cartridges are shot. Gutting out the junk and replacing it with a new Electric Condenser mic element and CAT5 cable with an appropriate plug, brings it up to date.

Wired it to my Tram D resulting in booming audio and positive radio checks from everyone I talked with just as it was designed to do with the Tram D, perfect match I could not be happier. My vintage radio shack is looking great.

The Astatic Corporation is a commercial audio products manufacturer founded in Youngstown, Ohio in In , two amateur radio operators, Creed M. Woodworth, W8AHW began experimenting with different types of microphones for their “ham” stations. Their mutual friend, Charles Semple, worked for Brush Development Company where he had been experimenting with Rochelle salt crystals. Semple demonstrated some crystal pick-ups that Brush was working with, leading Chorpening and Woodworth to found The Astatic Microphone Laboratory, Inc.

Semple was brought into the company as general manager to manufacture and market the company’s model D Crystal Microphone as well as other crystal microphones, crystal phonograph pickups and recording heads.

The original crystal element is dated Dec and still kicks butt! Some minor scratches in the brown paint, but the mic looks great. Astatic didn’t scrimp on.

Like the condenser microphone, this is also a type of pressure microphone, and responds to sound pressure. Shown at left is a section view of a dynamic microphone. These microphones are known for their durability; they are less fragile than condenser microphones, and are able to take in much louder noises before they begin distorting the sound.

They are often used by musicians performing live, due to both their ability to handle louder sounds and their physical durability. Though this microphone type is not in wide-spread use today, it is the most common microphone type in the Steele Collection. The collection contains Dynamic microphones, a large selection of which is shown in the galleries below.

The galleries are sorted both by polar response and manufacture date, if known. Microphones with the Omni-directional polar response type are the most numerous of the Dynamic microphones in Mr. Steele’s collection. Slightly less numerous in the Steele Collection than the Omni-directional Dynamic Microphones, the Cardioid Dynamic microphones range from to This type of microphone picks up sound from primarily one direction. The gallery below contains most models of this type found in Mr.

I discovered a couple of Astatic D Microphones. See more old Mics. Introduced in , the Astatic model D was popular for its high frequency response which resulted in very intelligible audio. Its high output voltage was characteristic of crystal elements and its high impedance allowed for direct grid input. The case thickness was reduced in April and smaller tags were then used and the ring holes eliminated. In , an eagle and shield was added to the rear cover to commemorate the US Bicentennial.

Other variations appeared from time to time until , when production ceased, 68 years after the first D was offered. The D is often used by CB radio hobbyists and vintage amateur radio enthusiasts as part of their operating activities. At a hamfest or flea market the seller wants to dispose of items in the most expedient way possible. To say that it worked the last time they used it is a good use of plausibility deniability for the seller but bad for you the buyer.

As early as , Fessenden had been experimenting with mechanical transmitters – high frequency alternators – as a source of a pure continuous wave carrier for voice transmissions. In Dec. By inserting a water-cooled carbon microphone into the antenna feed, Fessenden could voice modulate the alternator’s output. The system was demonstrated on December 21, Fessenden then decided to test broadcast a short voice and music program on Christmas Eve.

I started out with a Shure 55A, still the pride of my collection, and went on from there. I now have over 20 vintage microphones dating from the s to the s or so. There’s so little information available to the vintage mic collector, I’ve found. I have not come across a decent book on the subject, which surprises me because there seem to be quite few collectors around. None of my mics are for sale and I’m not really in the market for more right now, but I’m always interested in learning more about these objects and the history of the companies that made them.

Shure Brothers got started in the early ’30s in Chicago. In Shure introduced the 55 series of Unidyne microphones designed to limit feedback problems with a true cardoid response profile. The 55 series is still in production. When people think of a vintage microphone, this is usually the one they mean. Big and silver, the 55 is a true American icon.

I have a ish 55A, the low impedance version. The first 55’s were the 55A, 55B mid-impedance , and 55C hi-impedance. In these three models were combined into a single multi-impedance model, the The large-bodied 55’s were replaced in by the smaller 55s, the Elvis mic.
