Current shunt Question
« on: September 13, 2016, 05:14:26 pm »
Hello forum :)

I'm currently trying to fix an old Daub audio amplifier with more ore less success.
This amplifier has 2 Channels and dedicated to each is an inrush/overcurrent protection Board and one is totally broken.
I'm now thinking of running booth transformers of one of this boards since i have relays that fit in the footprint and can handle about 2.5 the current but obviously the current sensing has to be upgraded too.
If i'm right i only have to solder the shunt resitor from the faulty board in parallel so it will trip at double the current it would normally do.

Attached a picture of the schematic and the shunts in question in the blue circle R36 R37

Greetings Dennis

Edit: The traces on the PCB are also thick enough to handle the current (about 10-25mm in the relevant area)
