A few weeks ago I was contacted by an AudioKarma.org member about his tragic Pioneer SX-1010. He had the receiver completely restored beautifully and in shipping had the power supply board damaged. After sending it back, had another board installed and upon return shipping again the power supply board was damaged again. This last time it was cracked across the board. Living a distance away but willing to make a trip I will be restoring a parted board he obtained and install it in his receiver before he gives it the white glove delivery it deserves back home.
The pulled board is in very good shape. The foil side of the board needs a good cleaning as there is a flux mess but that will clean up nice as all caps, transistors, and diodes will be changed along with any resistors that may have drifted. Nichicon PW series will be used here as this board does get toasty under the receivers chassis. If you have one of these receivers be sure to open the bottom once and awhile and blow the dust out.
First thing done this evening was to go through the board and confirm all cap values against the service manual. This is a good idea with any restore as service manuals do change during a model series run. Next, replacement parts are ordered and luckily everything is in stock and on its way. Since I keep a good deal of resistor values in stock this evening I will check them to confirm they have not drifted and begin desoldering the board and cleaning it up.
Here is the board component and foil side before any work is done. There was an electrolytic already removed.
