where to find dual emitter resistors
I have an alpine amp that may be in need of a new dual emitter resistor in the output section but i'm having trouble finding the correct value. I believe its a 5 watt .1 ohm . The lowest i could find was.22 ohm .I'm sure mouser or digikey carries them but i'm having trouble locating them on their sites.

The Alpine part number is:

Circuit city is supposed to have it. I didn't know they sold parts.

wow they charge an arm and a leg for it too. 5 bucks plus 7.45 in shipping.Thats one expensive resistor. Is it possible to use two 5 watt .1 ohm resistors in place of the dual emitter resistor?

Two individual resistors will work.

You didn't give the model of the amp. If this resistor is one of several in the defective channel and others are in 'parallel' with it, you should replace all of them so they match.

the amp in question is an alpine mrv-1000. I'm not positive that its (resistor) defective as my meter is having some trouble measuring it because the ohm load is so low. when i place the leads on the resistor my meter just jumps back and forth between 0 ohms and .3 ohms . I figured for the cost that i've seen the parts for it wouldn't hurt to replace them. This is the same amp i repaired once and then a month later one of the same output transistors failed again. I'm just trying to find a reason why it failed and have been unable to do so.
