## Questions & Answers

**Q: Is this an ac to ac adapter or ac to dc adapter**
A: This is fixed 240vac Uk plug adaptor giving you a fixed 9vdc output via the cable and multiple changeable plugs (to suit almost any dc power socket type). It also includes a short polarity switch cable to give flexibility of either centre -ive or +ive to suit your device 9vdc requirements. Important you get this right for most electronics to avoid possible damage from incorrect dc polarity. Also check your device current draw/rating is within the plugs output rating (measured in amps or milliamps). I use it for guitar effects pedals so is perfect for alternative to eating standard 9vac batteries.

**Q: Is this suitable for Roberts Stream 202 radio, 9v 1.3a centre positive?**
A: Yes the transformer comes with all the different tips needed and a way to reverse the polarity if required just read the instruction carefully and you should be able to find a way to make it work.

**Q: Is this an ac to ac adapter or an ac to dc adapter it does not specify in the specs**
A: Hi, this is ac to DC.
