Cambridge soundworks basscube 12

This youtube video shows the exact problem that i had with my subwoofer: http://www.youtube.com/watch?v=Uxr0X0kxVUY My solution was: So i had success fixing this problem with my bass cube which had the same problems as the video above. The problem was with the big 6800uf 50volt rated capacitors on the circuit board. its a simple fix. i bought the replacement capacitors off www.mouser.com. the mouser part number for the new capacitors i bought was: 647-UKW1H682MRD when you replace these capacitors make sure you connect them in the same direction as the original capacitors. easy fix, problem solved, sub works great now.

SOURCE: Cambridge Soundworks Basscube 12S only makes pulsing buzz noise

Hey! So i fixed my problem! This is for the BassCube 10
Like i said before i saw that the circut board was burnt near the diodes ZD3 & ZD4, and the resistor R63. Thanks to Deadly1 and BillRad62, i figured it out. The R63 is a 1200 resistor, and the diodes are 15v zeners. I went with 3x 5.1v zeners to replace ZD3, unfortunately Rip-Off-Shack (Radioshack) didnt have 3 packs of these so for the ZD4 i put a 12v and 5.1v. Which exceeds 15, but seems to work without a problem. Hope it helps!

SOURCE: Bass Cube 12 makes loud buzzing noise when turned on !

Hi Ok thanks. I cannot be 100 % sure about this without seeing it but it sounds alot like there is a power supply issue, either bridge rec or caps. Caps are very often very obvious. If you get into it and have a look at what is normally the 2 or 4 biggest capacitors at the start/power supply of the board and see if they are ok visibily. If they are bulged, (often they actually explode and leave paper residue) then those are what need to be replaced. Have a look and see.

If its the bridge rec, it could be 4 diodes, fairly large next to each other or a square component with 4 legs out. Need a meter to test, but i would start at caps first
All the best

SOURCE: Basscube 10 dead...need zener and resistor help

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.

Has humming sound when powers on

You may have a power problem. Check to make sure that your wires aren't touching and not crossed.If this doesn't help try plugging in you sub to different plug could be getting interference electrically in the spot it's in

Loud humming noise

this may be result of blown capacitor - have it analyzed by applying strong magnet over the inside speaker , if humming persists, then its not blown capacitor -- the capacitor stores energy, and if that energy is lossed an out in the airwaves, thats the humming effect

Repetitive buzzing noise

Some componet in the Amp circuit is breaking down. The longer you let this go, the more of a chance that you will have a major short and blow out several parts,m as thats what happens with amps. Get it service asap and dont use it.
