8.66k It's the same as R104.

What is the circuit board designation for the caps?

Im sorry I forgot the number, it's beside the 4 DIP FET drivers, beside 2 output inductor, the other one I guess 2200uF/35V, do you think they must similar? the other one installed is just 10uF/35V.

I have some DLS schematics, in case somebody ask your help.

C408 is 1000uF@35v.

Hello guys!

I need your idea for this amp. why the fans didn't turn on upon power-up? is there any thermal turn on after reaching specified temp? I notice that after I remove the remote supply the fan turn on for about few seconds? its weird!

kindly help me which component on this amp manipulated these fans. thank you in advance! more power!

They are controlled by the signal level as well as by temperature. If you drive the amp to hard clipping, they should spin up. If you heat one of the various thermistors (like the one in the center of the transformer), the fans should switch on.

Thank you Perry!

how about the R106, didnt found 8.66k. 9.1 and 8.2 are available in the market. And physically R104 reads as 9.1k from the board.

8.66k is a standard 1% tolerance resistor.
