Question about Audio Players & Recorders
The unit has good rectification but on the 9V buss it has 15v and on the 4.5V buss it has 3.4V. There is no regulator that I can see on the 9V line. Is the transformer shorted causing it to output a higher voltage?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

SOURCE: Power transformer appears bad.
don't bother with a transformer. use a 12vdc 2amp power supply, the unit has a 8v regulator. remove the bad transformer and connect the power supply. polarity doesn't matter because the unit has full bridge rectifier that will provide the proper polarity.
