Cambridge Soundworks P500 Repair

[agabriel]

Hello,
I appear to have lost the fuse holder for an old Cambridge Soundworks P500 subwoofer during a move. That leads me to two questions:

1) Does anyone know which fuse holder the manufacturer sourced from? They had no answers for me - it was really disappointing...

2) If not, do you know how to get to the electronics on the bottom of the sub? I pulled the woofers out, but there is a wood barrier isolating me. I can't find any screws on the bottom and the case doesn't seem to want to pry open. With that said I didn't push overly hard for fear of inflicting more damage. If I can get in to it, I think it should be fairly easy to replace the fuse holder...

Thanks,
Anthony

A picture would help, as it may be a standard fuse holder. If not, chances are really good the amps are no longer in production and replacement of the entire amp is unlikely. Sounds like the amp is mounted from the inside during construction or glued into the cabinet.

I think it's this one:

I have attached a pic of the fuse holder. I'm going to try to find the part referenced, hopefully it is the correct one.



Thanks,

Looks like the one Rickster posted is a good bet.

Part is on order - I'll let you know if it works.

Wasn't the correct part... A little to big on the internals. I think I'm going to need to figure out how to get access to the controller. Does anyone have thoughts on how to do that? Has anyone done that?

perhaps one of these?

Or, if you can take some accurate measurements then Mouser is a good resource that will almost certainly have the part.

My other suggestion is rummage around thrift shops and garage sales until you find a piece of electronics that has the same holder and snatch that up for the fuse holder only.

To get access to the amp on the P500 or P1000 remove the rubber pads on the bottom of the amp. You need a narrow philips head driver to remove the four screws and the amp comes off.

I am having problems with the control module. I am using a different 12v ac adapter. When I connect it the green light comes on but when you turn the volume up on the control module to any level it automatically retracts itself back to zero. Could the fact that I am using a different ac adapter be causing this???

If you are still working on this, I am abandoning the whole amplifier/controller section of my P500. You are welcome to any or all of it, including the fuse holder.

Hi there Barkerdw -- I'd be happy to take a shot at getting the amp/controller going for my son's set of speakers -- he doesn't have the controller. It's worth the longshot --- if you're willing, I can send you my email for details. Thanks. Dave

Did you find out if the 12v ac adapter was the problem?
