Paradigm PS-1200a subwoofer issue


Novice Member
Hello all!

I'm new to the forum and have a problem with my paradigm ps-1200a subwoofer. It would not turn on at times so I took the amplifier out and found 2 bad resistors (R90 & R91).
I tested with ohm meter and they both tested at 2.7 Kohm.

If someone have the same powered subwoofer, could you please check and let me know the correct VALUE resistors for R90 & R91? I tested main transistors and they're good. Schematic for this is nowhere to be found online:(. Any help is greatly appreciate.

Thank you!!

I contacted Paradigm and the tech told the resistor values: 3K ohms 2Watt for R90 & R91. Some model versions might be different.
