Question about Cambridge Soundworks BassCube 12 Speaker
My Basscube 10 died suddenly and I finally got around to taking it apart. Like a few others, I discovered that the board was burnt around the four zener diodes and the R63 resistor. Someone identified the zeners as 15V and the resistor as 1200. I am trying to purchase the correct replacement parts from Mouser but there are further identifying characteristics. What should the power dissipation and current be for the axial zeners? What type of resistor should it be such as carbon composition, film, etc and what should the wattage and voltage rating be? Any assistance would be greatly appreciated!!!
I had a similar problem with my basecube 12. around the zener diodes and resistors looked Burt out on the circuit board. i replaced all those components including resistors, zeaner diodes and capacitors in the area which didn't fix the problem. it wasn't until i replaced the big 6800uf 50v capacitors did the problem get solved.

The zener diodes are 1N4774, I believe they are one watt. Try 3 watt metal oxide for the resistors. You might as well replace the 6800uF 63 volt main filter capacitors and the 220uF 50 volt capacitors while you're at it. Half the time the heat that cooked your other parts takes them out as well.
