I dont have anything on this amp.

Okay I think I can manage with everything else but those output gate drivers are a big questionmark. Some Groundzeros had irs21844 so could I try the 8 pin version of it IR2184? Although I think the pinout is a bit different on these ones because the gates are controlled from different pins..I think, I'll try to measure and get back.

Try applying a very small amount of water to the top of the scuffed ICs. Can you read anything?

Post the pin connections that you can see. Include:

12v above negative rail
negative rail
pin connected to high-side source
output pin driving high-side gate

 

[mika111]

Okay the original output gate driver is irs2008 but don't seem to find anywhere..any idea of the equivalent for this?��

 

[Perry Babin]

They may not be defective. Look at the pin configuration for the ICs in the image below. Use the pin names to see where to place the probes on your IC.

Do both ICs read the same?

 

[mika111]

Okay I need to get the power side working before measuring

 

[Perry Babin]

The measurements in post 25 are to be done with no power.

 

[mika111]

Oh my fault, yes I'll measure those. Some info said that IR2008 could be replaced with IR2104 or EG2104

 

[mika111]

Both ICs gave same readings:
Measure
1: 9,9k
2: 11,8k
3: 1,9k
4: 1,1M
5: 1,0M
6: 1,1M

 

[Perry Babin]

It looks like they're probably OK but I'd suggest that you lift pin 1 on each IC and measure #3 with the probe on the lifted terminal and a 3rd time measuring to the pad for pin 1.

 

[mika111]

Sorry do you mean measure VCC-COM ?

 

[Perry Babin]

Yes

 

[mika111]

Quick question: can I replace MURA115 with MURA120 ?

If you don't get any definitive replies, start your own thread. After about a dozen questions and answers, we may be able to find what you need.

I did start one but no answers I'm going to head down to my local shop today and hope they have one laying around just to get a view of the top of the board but I know it's a long shot.
