I plugged it in when i got it and it lights up, eye tube works, but I never put it to use. I'd tell you the model number of mine, but I will have to dig it out of my storage shed. |

One may get away with reforming a cap to save a couple of bucks, but I'm more concerned about the collateral damage if this reformed cap returns to its leaky state and perhaps wipes out a power transformer. |

Doesn't the capacitors show the same effect as being leaky ? From my understanding , the you start off at low voltage so the current will not be very high and as the capacitor forms you up the voltage some so the capacitor does not draw too much current. My understanding is that the plates of the capacitor form a coating (for not having a better word for it) on the plates when put under a DC voltage. I still believe in just replacing the 'bad' ones. Sometimes more harm can be done to the equipment by doing the reforming process if done wrong. |

Like to ad a problem of my own. I'm a retired electronic tech (30+years) but have forgotten everything I knew about radios, AM/FM/SSB. A friend has me looking at her Bose Wave, model AWr1-1W. All it puts out is an annoying loud buzz.Volume control do nothing. Even the power switch is useless. I did open it up, looked for loose connections, broken or burnt components, etc. Blew all the dust and dead bugs out. Is it even worth repairing? Any idea as to the problem? Thanks in advance. |
| jurb6006@gmail.com: Aug 26 11:51AM -0700 Not sure if it will help but electrotanya has one of them. https://elektrotanya.com/bose_wave_radio_series_iii.pdf/download.html Now listen, when you go to that site do not click any pictures, they all lead to junk. What you want is right under the picture on the left. It says "processing" and it makes you wait a minute or something like that. The word changes to "download". Click that and nothing else. It used to change to "Get manual" but apparently they decided to change it. |
