Hi. Been a member here for a wile. But this is my first post. I bought a mark iv it came with the 776 microphone That needs to be wired. It is the one with the brown strip. From what i read this is the one that goes to the mark 3. Would this mic work on the mark iv? Thank you.

The 776 was made for the Mark IV, the Mark III used the EV 'banana' microphone.
Assuming that your 776 microphone is wired with original colors, the plug wiring is:
Pin 1 - White
Pin 2 - Black
Pin 3 - Shield
Pin 4 - Red
If you need any help, let us know.

Hi, cbrown Thank you for your help. I sent fixr a email and he was nice enough to help me with the parts i need for the 776 mic. As well as trying to get the ping back in the old browning to work. Ill let you know how it go's.

I have a late model Mark III (1977) that came with a 776 mic. I never used it much because I prefer a D104 instead. The 776 is still in the box.

The 776 is a great sounding mic on the Mark III. I tried a non amplified D104 and the 776 on my Mark III and it seems that most reports are favoring the 776. I would imagine allot has to do with the persons voice that's behind the mic. I have never used anything but a non amplified D104 on my Trams, then again I have never had any other non amplified mics besides the 776 and my Heils. Sniper

cbrown is right, all of the versions of the MarkIII came with the Electro Voice banana mic. I thought that the 776 was amplified or speech compressed. Could be wrong, I've never seen one. The Mark IV's were the first Brownings to use the 776. I would never use an amplified mic on a Browning but I'm not sure about the MarkIV and IVA. My experience stops with the MarkIII.

The 776 is amplified; the Mark IV series radios feed the voltage to the preamplifier boards in the microphone. I'm not sure about the compression, though. Depends on which preamp they used.

Cbrown I have a 776 on my Mark III that I do believe is totally non-amplified. I saw a friends 776 on his Mark IV, and it has a hole in the underside of the base that can adjust modulation (I believe it's a mod adjust), but mine is plain with no adjustments whatsoever. I have a notion that Browning must have used at least 2 different versions of the 776, at least I have now seen 2 different versions. Sniper |

Ok, Sniper! I think you've got me on the right track about those mics since I've not seen one. That probably explains the different colored stripes where they're marked "776". I know that fixr can set me straight. I'd like to try an unamplified one on my Brownings and compare it to the D-104 G stand and bananna mics. The locals all tell me that the G-stand and bananna mics both sound exactly the same, that's until the element in my bananna one went bad, then I somehow lost the base for it. Don't know if I'll order the heil replacement for awhile, too many other projects going so I'll put that on the back burner.

Tombstone if you do find a replacement heil element try the #4 element in it. Everyone tells me that my heil with the switch set on the #4 element sounds very close to my non amplified d104 when I use it on the Tram. I will have to talk to my friend Dave (wopchopper unit 1069) to see how his 776 mic is painted as far as the stripes, now you have me wondering if his is painted differently than mine. My 776 is gold in the insert with the name browning on the left side of the gold insert (with no capital b) and then off to the right are the three dark brown slash marks like a racing stripe. Sniper

I've seen two versions, one with brown stripes and one with red, but every one I've encountered had the preamp board in it. Admittedly this amounted to maybe a dozen or so of the 776 microphones, so it's possible they made some without the preamp boards. I'd be kind of amazed if they did, and used the same model number, though. |

Well cbrown I was so doggone curious now that I had to take the base plate off and sure as heck there IS a board in there with a variable pot, just no hole in the base cover plate! All in all this mic works great with the Mark III as I stated before. Sniper |

Now I'm really confused on the 776 mics. They must all be amplified or speech compressed. We've already determined that there are different versions of it but why would some have the hole for the adjustment and some don't? Heil makes two models of elements for the bananna mic that I know of. One is intended for cutting through noisy skip conditions and the other is more mellow sounding for working the locals. When and if I get ready I'll remember the #4 model since reports say that it's the closest sounding one compared to the D-104 G stand.

Tombstone if you do find a replacement heil element try the #4 element in it. The Heil HC-4 is a great SSB element, I agree. It really guts through the crowds. The HC-5 gives less of a punch at 2,000 Hz, which makes it a better general element. I've done a lot of HC-5 into D-104 head replacements. |

We've already determined that there are different versions of it but why would some have the hole for the adjustment and some don't? I'll pull the 776 mics I have here apart (both are the red striped 776, so no preamp adjustment hole) and take a look at the preamp. I'll also pull a Turner Super Sidekick and a +3 apart and compare them to see which preamp they used in the 776. I'll try and get it done tonight. I did pull one 776 apart last night to photograph the innards and the base cover. Seems like Turner just used a bottom plate on some 776 mics that didn't have the hole punched. The preamp still has the gain control. .JPG) .JPG) As for why they eliminated the adjustment hole, I can just speculate. They might have done it to keep the masses from pumping up the gain so it didn't distort the clear audio the Browning radios were known for. |

Not to familiar with the MK4's was this the stock mic that came with the radio?
Also is there a range of time the mic with out the hole showed up
i.e mic has hole then no hole then hole comes back?
Could have been a manufacturing issues Turner may have ran out of the bottom plates with holes and just used what they had till the correct ones came in. There may have been a production time frame they had to meet. that would explain why the paper shield has the hole. or maybe not.

Cbrown that IS exactly what mine looks like on the inside and mine IS the brown striped 776 mic. So now it seems as though we have red striped and brown striped 776 mics that are identical without base plate holes, and then you have some models that DO have the base plate hole. There doesn't seem to be any given rhyme or reason why browning or turner did what they did with these 776 mics. There just isn't a pattern forming here. I could see if all the brown striped mics had no base hole and all the red striped ones did, then we could call it a pattern of sorts, but what we have here, there is no pattern. Sniper

Okay, I pulled apart both a Turner +3 and a Turner Super Sidekick last night a took some photos. The most interesting thing to me was the PCB ID is the same on all the microphone preamps - EIA-151-1. Here is a close up of the board on a +3:  Here is the photo of the +3 preamp in the microphone. Notice no hole on the PCB for a gain adjustment.  And here is a photo of the Super Sidekick preamp. The PCB is exactly the same as the Browning 776 preamp.  I didn't do a component check, but I imagine there is a bit of difference, seeing how Browning feeds 5 volts to the microphone while the Super Sidekick uses a 9 volt battery. Don't mind the wire colors in the bases; these are my working desk mics and I replaced the cords years ago. Inside the base on the bottom plate is a label with the colors labeled for what they are. I always do that is I can't do an exact cord replacement. Saves me headaches years later.  |

I'll have to pulll the bottoms off of my +3 and SSK and do a component check as well. Supposedly the SSK preamp is not a compression circuit like the +3, and the 2 pots are a coarse and fine level adjustment. I'm pretty sure there's a difference in mic element between the 776, the +3 and the SSK as well..... |

The Turner +3 had 'Modu-Gard' which was a type of compression, with a ceramic element that had a frequency response from 300-3,000 Hz.
The Super Sidekick had a dynamic element with no compression with a frequency response from 300-3,500 Hz. Plus the preamp had way more gain.
I'm not sure what element they used in the 776, I'd have to pull my spare one apart and take a look. I'd have to be careful because that's my only backup 776 I have.

Don't kill yourself taking mics apart. I think that we pretty much know what's what now except for the element thing. I have two sidekicks here. One's a mess electronically but cosmetically nice. The other is a mess cosmetically so eventually I'll build one nice mic out of both. Too many repairs around here to keep up with.

Interesting on the frequency range ratings on the +3 and SSK. The SSK is rated with a higher frequeny response, yet every SSK I've ever seen or heard has been far bassier than the +3. I guess the frequency range only tells part of the story. The rest of the story is told by the actual response curves. |

Very true. I like the Astatic D-104 head, but I really prefer the 10-DA. More bass to it, and it really excels for SSB usage.
Still for the most part I like Turner & Shure mics. I do have some Heils and one Sennheiser that I'll use also.

I think the number "151" was Turner's member number in the EIA, Electronic Industries Association.
Mallory was "235", RCA was "274", GE was "188". Best I can tell, the dash and last digit would be the actual facility where the part was made, for a company with more than one factory.
Old USA-made capacitors would often bear that EIA number followed by the 4-digit code for the production date. Two digits for the year, followed by two digits for the week 01 through 52.
