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



No. If you have no idea how to solder you will make a right mess and
possibly destroy the PCB. At best you will get a dry joint.

Do some Googling on soldering techniques, then practice on an old radio or
something.

Then Google some more on power supplies.

Then get a multimeter and measure your amps power supply.

Then maybe put all your new found knowledge to good use.
