Sony TA-VE170 PSU and Standby

Based on conventional transformers, the power supply is impressive. Almost no ripple on any of the voltage rails. There is a wonderful Bando low profile transformer as the main transformer, and another smaller transformer for the standby power supply. You can see all of this in the following sections of this multi-page article.

I just love this low profile transformer. It seems to work really well in this design.

This smaller transformer is for the standby power supply. The infrared receiver circuitry, and the power button, require standby power.

The standby power circuitry is a very simple and elegant design solution that seems to work well.

These large electrolytic capacitors for the main power rails work well and are reliable.

The Bando Company is the best in making transformers. These are very reliable -- well, so far so good -- we will see in 60 years time.
