Sony SQA-200 amplifier

Here is closeup of SQA-200 US version showing power supply and amplifier assemblies. Same power amp module is used in TA-70 and STR-202 models. Metal bracket with ring on power supply board mounts TO-66 transistor. Notice main filter capacitor bracket-screw is accessed via notch in power supply board. This practice was used in some later Sony models as well; example is TA-3650.
