3DJ7F (TO-39) ???

[Jazzy_Pidjay]

Hello everybody !


i'm on tracing the schematic of a microphone
from L*a*n*g*e*v*i*n.

And there's a small TO-39 inside
with 3DJ7F inscribed on it

i can't find any information about this !!

what is it ???

thanks ! :thumb:

Hey, tu enchaînes les projets ambitieux ! Tu penses utiliser quoi comme capsule pour le Lαngεvιη ?
I love this name: « Lαngεvιη », it sounds so french. :green: It could be a cheese name?

i have tested it with the Peluso CEK-367
sounds good, but after many tests and comparatifs
the modified L*a*n*g*e*v*i*n had less Low-End than the G7
or the TLM103.

i think i'll go to change some capacitors, listen how it sound
and perhaps change the capsule with another brand
or test it with the TLM103 capsule. The circuit of the L*a*n*g*e*v*i*n
seems to be better than the TLM.

Je l'ai testé avec la capsule CEK-367 de Peluso
il sonnait bien, mais après quelques tests comparatifs
il s'avère que le L*a*n*g*e*v*i*n modifié possède moins
de basses que le G7 ou le TLM103

Je penses que je vais changer quelques condensateurs,
écouter comment il sonne et peut être changer la capsule
avec une d'une autre marque ou tester avec celle du TLM103.
Le circuit du L*a*n*g*e*v*i*n semble mieux que celui du TLM103

:green: i'll name my mic, cheesy L*an*ge*vin :thumb:

Hi Jazzy,

There is no reason to mask names of manufacturers, like L*a*n*g*e*v*i*n.

It makes searching impossible, and we don't want to keep answering the same questions.

ok :?

i see people do that, so i do....

right i can write it normally now !

That reminds me a french Funk/Soul/HipHop label: « Big Cheese Records ».

Do you know is function in the mic-preamp?




Je vé me renseigner à ce sujet .

i don't know his function for now
i finished to trace the circuit later

and tell you more about that


thanks !

any other information about 3DJ7F ??

Sounds like a manufacturer's internal part number, unfortunately.

Is there any logo that might indicate the manufacturer?

Probably the best policy would be to get (or as you are doing, make) a circuit diagram and have us determine the likely characteristics based on how it is being used.

i see on another forum
than a user of a Rode, see the same 3DJ7F inside it.

i think it's a sort of FET transistor

the component is between a 1000 Styroflex (from the capsule)
and a 1G resistor... so it seems to be the place of a FET
i'm tracing the circuit now.

Any idea about the compatibility of different FET ?
what the characteristics of a FET ?? voltage ? gain ?

thanks
