Sony boombox model cfs-b11 transformer

I have a sony boombox model cfs-b11. The transistor is beyond repair, and I cannot test it to find the output voltage/amperage ratio. Do you know the correct output ratio the transformer should have?Thanks.

Sony cfd-s01 boombox radio


Hi Bart,
You will find there is a specification plate on the rear of the unit.
It should have a rating on it showing the wattage of the unit. This is usually the amount needed to operate all the functions of the boombox.
The wattage is your input voltage multiplied by the current draw in amps. So the amperage is the rated wattage of the unit divided by the input voltage.
Usually all power goes through the transformer, so I would use this input amperage as a guide, and assuming there is no power loss, use the same calculation for the output - you know it is 9 volts, so the wattage going to the unit is the same as the input wattage, so you can calculate the amperage from this.
Transformers usually work on AC input/output, so there will also be a rectifier to convert the AC to DC for your boombox.
I would add 10 - 20% above your calculation to make sure you have sufficient power. Also I suggest that you install a fuse between your transformer and the boombox for safety.

I can't power up the Sony CFD-S350 CD/radio/Cassette/ boombox after the electrician did some faulty wiring to the building.


You will need to get the transformer replaced. This is something a person who can service power electronics can do. Please visit your local electronics repair shop for service.

Bad transformer? Sony CFS-W338 boombox


More than likely there is a voltage resultor in the circuit that will take the 24V input and convert it to 9V internally. This voltage difference is not necesarily a problem. What is the problem with the unit that is causing you to check the voltages?
