JL Audio RD1000/1 Part ID

[peeby]

So R46 (see pic) reads 11.6K out of circuit.

Not sure what these markings mean?

 

[Perry Babin]

Is there one in the other half of the output section?

If it's elsewhere, post wider images.

 

[peeby]

Yes. However that is the one that burned.

R427.

 

[Perry Babin]

If the common connection point of that IC also goes to the supply pin of a driver IC, I'd guess that that's a 10 ohm resistor.

 

[peeby]

It is connected to Pin 6 of a IR2101.

 

[peeby]

Correction - Pin 2 of a 2101

 

[peeby]

Wait, it is an HIP2101 halfbridge driver.

 

[Perry Babin]

I've seen the HIP2101 in some JL amps but neither the IR or the HIP2101 seem to work in the configuration I expected. The older amps used the 4427 driver and the resistor/capacitor connected to pin 6 of that IC would make sense. If the IR2101 is original, I can't help.
