MTX resistor Thunder 4405

Solosound · 20th July 2008, 01:57 AM

Please help me.

I need the rigth value for R943.

The amp had burn one fet, this resitor and 3 more resistors 22ohm .

Perry Babin · 20th July 2008, 02:15 PM

The large resistors are 0.22 ohms.

If the resistor to the left of the burned one is 200, 220 or 221 ohms, the burned one is probably a 332 ohm.

Sorry, I forgot to write: .22

I found Q915 in short too.

Now all the amplifier is working properly.

thanks to Perry and its patience.

value resistors R918, 919, 934.

If no one else replies, post a photo of the area where the resistors are located.

How this will help? They were burned, not visible markings. You have a scheme?
I'm sorry write through the translator.

I don't have a schematic diagram or any information on that exact amp. I may have something similar that will help but I need to see what you have.

918 and 919 are 475 ohms. 934 is 221 ohms.
