JL 500/1v2 amp Burned Resistors

[stevepersell]

As title says, i have burned the resistors and Transistors on the Power side. I've ordered the replacement transistors and am stuck on the resistors. Can someone help me with ordering the correct resistors? The ones on the amp are burned up and am not able to read the color value. Any suggestions?

I haven't repaired a V2 but the power supply gate resistors are likely 47 ohm, 1206 (size) components.

Mouser:
71-CRCW120647R0FKEB

If you're not sure of the size of the originals, use the lead spacing of the SMD ICs. The one on the left is 1206. The one on the right is 0805.

This is the type of resistor that i'm looking for...I hope i'm not reading your post wrong. The link to the picture you posted looked like a flush mount resistor and that's not the one that is burnt on my amp.

Thats what the resistor looks like that is burnt up on my amp.

I hope i dont sound like an idiot.

also, Thanks for replying!

The resistor is directly infront on the Transistor...I wish i could put a picture of the items that are bad up...but there are no pictures of the JL's internals online.

When you say the power side, are you talking about the power supply section or the audio section? What was the original number of the transistor(s) that were burned up?

[stevepersell]

When I said power side...I ment the side with the power terminals...however, Im pretty sure it's the "audio" transistors that are bad. The transistor numbers are IRFZ44N I think...I'm at work and recalling from memory. I was able to find the correct replacement for them, just not sure what the resister values are.

[Perry Babin]

The Z44Ns are the power supply FETs.

The following resistors are through-hole components similar to the one you posted. The top one is a 1/8w. The other is a 1/4w. Look at the dimensions and order the one that fits your board.

Mouser:
299-47-RC
291-47-RC

If these resistors connect to the gate leg of the IRFZ44s, the 47 ohm resistors will work.

This is a picture of the board and im pointing to where they are on the board...I'm pointing to transistor on this one.

[stevepersell]

...and here is a picture of the Resistor.

[stevepersell]

Are most of the amplifier resistors 5% tolerance or 1%?

[stevepersell]

Ok, so i just took out the resistors from the board...they are burnt but would the reading from my meter be different if they were burnt? I'm getting readings randing from 70 ohms to 96 ohms from the different resistors i took off.

Here is a more detailed pic of the resistors on the board.
