At least as long as the original pole did hopefully, but it would have lasted forever if they thought to use both contacts simultaneously when they assembled it. I've seen crappy stereos use half a switch as well. |
| KenO <kenitholson@yahoo.com>: Dec 23 10:10AM -0800 Thanks everyone for your comments. Guess I need to elaborate so will try. Michael Black: I was unable to see anything turn on with either batteries or AC when pushed the power button On and Off a number of times. What tests do you suggest I run? Arfa Daily: "If the unit uses a 'figure 8' AC socket, this is the first place to look...." Again what tests do you suggest I run? Can I post a JPEG of the AC socket? Bruce Esquibel: "not sure what you'll learn from the experience..." At this time do not know. If nothing else will use it for parts. Was surprised that it does not look like it was abused so am tending to agree "It was real low end shit..." Am still surprised I can not find a service manual or basic schematic for GPX C971? These have to be somewhere out there? Maybe under another Name? Any ideas how to identify the Chinese Mfr? Open to all suggestions. Ken |

Highly unlikely there was ever a service manual for something like that. > These have to be somewhere out there? Maybe under another Name? nope. > Any ideas how to identify the Chinese Mfr? It probably came out of a grade school. > Open to all suggestions. You don't really need a schematic to fix a boombox, and if there was one, it would probably be wrong anyways. Here's a checklist to start with- without even trying to be a jerk: Does it power on? Is it plugged in? Is the cord good? Is there power making it to the power supply? Does the power supply work? If not, what's broken? replace bad part, try again -Or- fire t up with bench power supply. If other stuff is broken, just toss it unless it's of sentimental value. |
