ARC Audio KS 900.6

Anyone know if all of the resistors are 5.11 ohms ?

Or happen to know the value ?

They sit behind the speaker terminals

 

[Perry Babin]

That's probably right. Contact ARC if no one has a definitive answer.

Yeah, they are 5.11. Make sure none of those zobel caps are shorted too?!

 

[caraudioguy2100]

The resistors are 5.11 ohm wondering if I can use 5.6 ohm resistors somce I have them on hand ?

 

[Perry Babin]

It probably would not make a difference but why not order the right parts?

 

[caraudioguy2100]

The resistors that are burnt are actually 10 ohm resistors .

I confirmed this with arc audio .

They burn due to clipping

 

[Perry Babin]

It's generally either abuse (long term hard clipping of the high frequencies) or oscillation. The sub channel doesn't generally burn because the low-frequency clipping doesn't pass much current through the zobel network.
