I had a guy contact me about fixing his Playchoice 10, upon checking things out, I've come to the conclusion that the power supply needs rebuilt/replaced. I've done a lot of searching in the last 24 hours, and I'm trying to find out what the difference is between the PP-7A & PP-7B power supplys are. I don't have it in front of me at the moment, but here's a photo pulled from the net of what it looks like. This is the PP-7B right?
I've found a few threads talking about the different caps to get for replacements:
Then followed by this comment:
As I don't have it in front of me, which caps are being refered to? I'm just trying to get a head start at tracking down what I'll need. Also, I'm in need of a button replacement for the Reset button on the cp:
To any and all who help, thank you

To add to this - since this is a switching supply, you MUST use low-ESR type caps for the Vout caps of the regulator circuit.
