I have never soldered electrical components, that I can remember. 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.

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.
