MAY 16

Well...we're cruisin' right along here re-building the stock. We will be completely restocked again on Tuesday the 20th. I would have liked to have been re-stocked by Friday, but we've been taking our time to make sure we get it right. As I said before, our primary goal is to continue to provide the "gearheads" of the world with the finest mic gaskets available anywhere. I think we've done just that.

There will be a price increase to $10.00 per gasket effective Tuesday May 20, 2008. I deeply regret the increase but it is necessary.

On a happier note, you will be noticing some exciting additions coming in the next few week...they will be happening slowly, nothing drastic so pay close attention. I'm not going to let the cat out of the bag just yet, but you're gonna love it...trust me.

As always, if you have any questions or concerns, please feel free to email me or call me anytime on the phone.

Thanks for your support and your patience.

COMMON GASKETS $8.00 MC 127/151 CR/CM Astatic JT-30 New Style (post war). This gasket also fits the Honer Blues Blaster and CAD HM-50 SEE MIC PICTURE Astatic JT-30 Old Style (pre-war), JT-31, JT-40, Model A. Older JT-30s have a brown or hammertone finish, and often have a riveted label. Some old JT's do have a sticker label. The best way to determine whether you have an old one or a new one is to do the "quarter test", as shown below. SEE MIC PICTURE Astatic Biscuit ( Model 30), Calrad 400, Argonne AR-54 SEE MIC PICTURE Astatic T-3 SEE MIC PICTURE Astatic 200 SEE MIC PICTURE Shure 520, 707, 440 Bullet . This gasket fits both small and large Bullet shells, including everything from the old Brown Bullets, Brown "Recording" Bullets, and the more modern 520D and 520DX shells. SEE MIC PICTURE   Turner desk microphone, Including the +2, 250, 251, 252, 253, and 454. They're sometimes referred to as "shark fin" shells, because of the large decorative fin on top of the mic. Older shells, like the Turner CX and BX also have the fin, but this gasket won't fit. You'll need the gasket below for those. SEE MIC PICTURE   Turner CX, BX, BD, and RCA Challenger SEE MIC PICTURE   EV 605/606. Designed to fit in 605 shells with the dynamic element mountings removed. See Picture. You should use a drop of super glue to hold the gasket in the shell, as there is no flange area to secure the gasket. Some users leave the mountings and cut out notches in the gasket. Either way is fine. SEE MIC PICTURE COMPARE OLD AND NEW 605 STYLES   EV 605 (old style). This style of 605 has no mountings and is a little too narrow inside to hold a CM with a gasket. This is not a gasket, but a plastic retaining ring that will set behind the CM element and hold it in place without a gasket. I believe this ring will also fit the 630, 612, and other EV mics.   SPECIAL ORDER GASKETS     Shure 520/R7. This gasket will hold an R7 element in any Shure Bullet shell. The R7 form factor includes the following elements: Shure R7, R3, 99-131, 99A94, 99B94, 99A400, 99a404 Calrad DT-51. Please allow 2 weeks for delivery.   Astatic ceramic element sold on JT30.com. I can mate this element with any shell. Specify your shell along with your order. Please allow 2 weeks for delivery.

HMG News, Tips, and Errata

Note: There is a slight difference between older JT-30's and newer ones

To determine which style you have, turn the mic grill upside down and measure the space between the gasket seat and the notch using two quarters. The old style will be approximately the depth of one quarter (1.75 mm), the newer style will be approximately the width of two quarters (3.5 mm). Some really old Astatics like the model A, have no notch at all. Those will take the old-style gasket.

 

 

Got a 151, 127, or R7 crystal that shakes like a maraca? I need 'em. They make great molds for gaskets. I'll trade you a gasket for two dead elements. Sorry, I don't need any Astatic 101, Argonne or other oddball crystals.

As long as I have the gaskets in stock, I will mail your order out immediately. If it's been more than 2 weeks, there is something seriously wrong.

The gaskets are made of a synthetic urethane rubber, not a silicone or latex. It starts as a liquid at room temperature, and hardens when mixed with a chemical catalyst. This material is used for medical prosthetics, theatrical special effects, and mold-making. If the gaskets are fresh out of the molds, they may have a slippery surface (a silicone demolding agent), which can be washed off with soap and water or denatured alcohol. When the rubber is fresh, it's got a pretty pungent odor, but it fades quickly. To help the process along, wash the gasket with soap and water, then dust with a coat of baby powder (straight from the manufacturer - who knew?). Wipe off the excess and you'll be ready to go.

As of this writing, I am experimenting with a new silicone rubber compound. It's more expensive and harder to mix, so we'll see. I should be sending out the first batch within a couple of weeks.
