I have a Sansui 9090 that I was told has 4 diodes that sometimes go bad, and since I have no switched power, one may be bad. First, does this sound right? Second, would it be a good idea for me to clean the dust off my cheap soldering iron and try to replace them? Or test them all first? Can I hope to find replacements? What area of the unit should I look for them in, have not studied this thing yet. Help is appreciated. Dennis The 9090 wasn't known for defective power supply diodes but it had a major problem of 2 1 ohm resistors opening up causing a dead receiver. Chuck I guess the idea is to check most everything on the front end of the power supply. Check first, instead of, replace all first. Description abouve sounds like a turn on delay using some resistors. greg |
