Could you link to your source of the amp?
This is a SPF5189Z amp. Many are available on eBay but make sure you buy from a reputed seller and check the current drawn as there are many fake SPF5189Z components on eBay.
Officially it should run from 5V/100mA but for low input levels 3.3V/70mA works as well.
They work well below 50MHz
