There are different types of power supplies. The original Sony power supply is a linear type. This UpBright power supply is a Switching type. Linear type power supply tend to be HEAVY because it contains power transformers. Switching type power supply tends to be LIGHT in weight. Guess which is better for audio application? Linear, because it reduces or eliminates the ac hum. Switching type power supply adds to the ac hum. Avoid.

Receiced on time, seems to work. Sometimes shortsout bad fit.
