Kicker DX125.2

[cajones65]

I am looking for the resistance value for R74 and R84 for this Kicker DX125.2. Maybe someone has a picture of the guts. Thanks

R74 & R84-10 ohm .25 watt. They carry the Rail voltages to the +/-15 volt regulated supply. Check Q23-D669 and Q28-B649 and associated components. Also, Check for any shorted opamps on the preamp/xover board.

Thank you PapaZBill

PapaZBill, is there suppose to be 116 ohms between the v+ and v- on the op amps on the pre-amp board. (NJM2068L)?

 

[cajones65]

There is also 116 ohms on U8 2060D op amp.

There is a shorted opamp. Desolder Pins 4 and 8 of each opamp, starting with U8. After each opamp recheck with an ohmmeter to see if the resistance returns to normal,should be megohms. There will must likely be several failed opamps.
