[Tintin2005]

Hello Guys!

I need help to identify the components with the orange circle.. The diode , i suppose, it is a zener. it has 2 yellow circles . diode is not shorted but drives in the 2 possible directions.

The Jfet transistor i can´t find it anywere. it is marked J ... 4.

Can you help on this? with schematics or other usefull info?

If helps, i have a akg perception 120 and it has the same Jfet transistor. J...4

Sorry for the english.....
regards

Looks more like a 4148-type. Probably part of the phantom power protection/regulation circuit.

As of many years ago, AT schems are next impossible to find.

Hi.

Thanks for the answer.
Diode seems a voltage regulator. thansistor is the capsule amplifier Jfet type.
