Jolida SJ 502a service manual
I have one of these coming to me possibly damaged electrically. I have
a copy of the schematic that floats around the web but it doesn't have any voltage notations on it. Is there a copy of the service manual that is around to purchase? I haven't tried Jolida yet; thought I'd try the cheap route first. |

I haven't tried Jolida yet; thought I'd try the cheap route first. Don't count on an 'official' service manual or schematic to include voltages. A lot of them don't, these days. They expect the literature will be used by experienced techs who will know what voltages they should expect when they look at the circuit diagram, or can get them by comparing a working channel with one that's not. Nope, you should call Jolida. If i did have one I'd keep mum, figuring you can pay your dues like everyone else. However, I doubt there even IS one. Ad hoc containerload buying at its best. Not sure what you mean by that, Bret. There was an article in Forbes magazine a while back about Jolida's problems with quality control at the Chinese factory that builds their stuff, but the Chinese build it, they don't design it. The Chinese engineers I've dealt with aren't capable of sophisticated design. They also appear not to know how to operate their Audio One test sets - I've never been able to correlate my measurements with the 'Audio One' badged printouts they've provided me (their numbers are always better than mine, go figure ;-). The only way to get decent quality out of the Chinese is to have your own people on site. And they HAVE to speak the local language or they will be ignored and worse. Jolida has done exactly that, according to Forbes, and their QC has greatly improved as a result. I do consulting work for two companies that have also done that, with similar results in the quality of their products. But the 'Audio One' printouts I get are still bull****. Fred |
