Christmas has come early for me!!! I've just received a Browning Mark IV, you have to see this thing to believe it. Absolutely unmarred, scratched, dented, or molested. You can't see any wear on the face plate around the knobs, the chassis is shinny and show no finger prints even. The plate on the bottom shows no marks at all. In short, it appears to be right out of the box in 1977-exactly what I was looking for.
I'm not going to tell you how much I paid (lest you guys never speak to me again) but suffice it to say there will be no more Christmases for me for the next several years.
A couple of questions for you operators though; I noticed that 6 screws were left out of the rear of the transmitter case ( the 3 that secure the screen to the chassis, and 3 that hold the bottom plate to the chassis) the seller told me that these were removed, and left out because it effects the transmitter operation negatively. You guys would know, is this BS, or the real deal, that all Browning owners leave these screws out?
The seller also recommended that I send my NIB D-104 Final edition Mic I bought to use with this radio to Mr. Barkett, and have him wire it to the Mic plug, and also to electronically bypass the amp circuit thereby making it a standard, non amplified D-104 because when using it with this radio, the transmission will be over modulated and distorted.
What say you guys-you would know, do I need to defeat the amp circuit on the Mic?
Thanks, broke, but happy. Michael.

I don't see how the screws would affect the operation of the radio. If that was the case why would the company have put them in there?

Michael, Congrats on the new Eagles. Sounds like a reat beauty.  |

Yeah; I thought the reason he gave for the missing screws seemed strange. Maybe they are just stripped out, but I'll check to make sure there is nothing behind in the chassis that might interfere when I remove the paper he packed around the tubes for shipping, before replacing them.
What about the mic modifications, is that standard if you use it on the Browning?
Thanks, Michael.

You should be able to use the amplified D-104 but just barely turn the volume pot up in the bottom of the mic. I believe that radio came with the "776" mic that was either amplified or speech compressed. My experience with Brownings ends with the Mark III.

Scews affecting the radio? Sounds like BS.
I have re-built a many MarkIV PLL and all.
I would have a 100,000 mile tune up done for sure.
What I did for my Diamond Eagle D-104 is put the L-Pad
right in the mic plug. So you don't have to hack up the wiring.
This is on the cut sheet that came with most TUP-9 stands etc.
Works great on mine and then there is no need to bypass the amp. Most people prefer to just bypass the amp.

Bypassing the amp in the Mic woeks great for me and believe me. I've tried every modification and on a tubed radio, an unamplified D104 works best

Yes, I would say the seller is looking for his loose screws. (get it?) Getting away from the humor. Sounds like a nice find on your part. Welcome to the best site for classic radios. Good luck with the Eagle. 73 Gator  |

Hey Mark 4. I like the idea of doing the L pad mod at the mic connector. My experience with Brownings is to use an unamplified crystal mic also but doing the L pad mod sounds like it works well too. Browning on!

Thanks Tombstone, I noticed a more full sound using the L-Pad. This is Astatic's mod not something someone cooked up. As for a wide more punchy full almost studio sound. Nothing beats a good 776 mic On the MarkIV series. But these varied in the quality of elements also. I did some sifting and have the best of the best in sound. These mic's will smoke a D104. My studio headphones and anybody that has heard my sets confirms it. But to each his own  |

Yes, I know that the mod comes directly from Astatic, I've done L pad mods in the base of the mic a few times but I want to do it at the mic plug on an extra Silver Eagle that I have and see how it sounds on one of my birds. Sounds like I need to pick up a 776 mic also. You said that the audio quality depends on the element, are these crystal or ceramic?

I figure you knew the mod. Stated that here for other peoples benefit. As for the browning 776 it is neither crystal or ceramic.
It is a dynamic. It's the perfect match. But some of them like in anything have muddy sounding elements. But the majority sound great!

Anyone know where I can buy a good 776???

Ok, being that the 776 has a dynamic element, that would be the same as vocal mics for stage or band use. That would also explain why it has that warm studio quality sound. Are these mics amplified? Do you have to get right up on it or will it pick up with full modulation at maybe arm's length away like a D-104?

OK, you talking about using the Lpad on the 776 or D104...or either? I thought I beat this subject to death. Now you'rethrowing another curve at me...LOL....Go ahead...I'm all ears

The L-Pad is for the D104.
The 776 is a amplified mic. The orange stripe on the name plate was made for the MarkIV series. The brown stripe was made for the MarkIII. The only difference is the one for the MarkIV has 2 switches in the base. When keying up it supplied 5VDC from pin 4 on the mic socket.
The Brown stripe was powered by the keying circuit on the MarkIII.
And no you do not need to get up on the mic. They have allot of gain. And more than enough audio! There is a pot in the base of the mic you can adjust. The amp Board is almost the same as a Turner Super Sidekick. But not exactly. Tried one and the audio was completely different. Used the mic element from the same mic in a 776 with awesome results. (Same Part)

Hey guys; I emailed Mr. Barkett, and he said he would wire up my D-104 to a Browning plug OK, but says he does not install L Pads.
Question; What exactly is an L Pad, and can I wire it myself? I do know how to solder electronics.
Thanks, Michael.

The L pad mod is easy and the instructions should be on the wiring paper that's glued to the inside of the mic's bottom plate. If not, the Astatic wiring manual has it.

I'm slightly confused. I thought that the Super Sidekick has a ceramic element. Was the 776 made by Electrovoice or Turner?

The 776, Plus Three and SSK mikes all used a low-impedance dynamic element, and a step-up transformer between the element and the input of the preamp circuit.

Thanks, 2600. That clears it up for me. If I find a brown stripe 776 and don't like the sound I now know that those two Turner models have the same dynamic element. I believe that the Tuner Plus Two had a ceramic element thus the more brassy sound.

The Plus 3 does not use a Dynamic element.
The SSK and 776 do. The Plus 3 uses a ceramic element. And has no transformer it it's design. I can post pictures of this if you would like. Also the amp in this mic is a high impedance design. They also advertised the Plus 3 as having a ceramic element. The SSK and 776 share the same transformer and pretty much the same amp board.

I refuse to sound like I'm contradicting anyone in this business, especially 2600. I found a website that has all of Turner's original specifications and pictures, looks like the papers that would have come with the mics. The Plus Three has a ceramic element, Turner calls the element the "front".

As I noted above.
And there are additional parts on the SSK amp board that make it sound different from the 776.
We all make mistakes sometimes. I'll be the first to admit it.
It's not about gotcha. It's about helping each other on here.
2600 has a wealth of knowledge. And I turn to him many times for help. No ego here.

Well. I've learned a lot about Turner and 776 mics on here. Turner mics seem confusing, thats' probably why I usually use D-104's for a communications mic.
