RADIO SHACK SPEAKER-AMPLIFIERS!!
We had a small supply of these amps for our customers. As it stands right now, Radio Shack is no longer selling these amps. We hope that Radio Shack starts making them again. These are ready-to-use mini amplifiers with built-in speakers. 1/8 inch (3.5 mm) input and output jacks. These amplifiers have a high impedance input and low impedance output. They work wonderfully with our one tube set, crystal sets, and foxhole radio. Perfect for science fairs because they allow everyone to listen to your radio project. These amplifiers are so powerful that they allow you to hear signals that are too weak to hear with headsets alone. The low impedance output can be connected to an external speaker, or use the built-in speaker, or connect low impedance earphones like the inexpensive modern headsets available today. Input impedance 5K ohms. Output impedance 4 to 32 ohms. Power output 200 mW. Frequency response 100 HZ to 10 KHZ. Powered by a regular 9 volt battery or external 9 VDC adapter which are not included. We recommend that you also buy the input cable described next for connecting this amplifier to your project radio. We like these amplifiers so much that we purchased them from Radio Shack before they stopped selling them, in order to make them available to our customers. We no longer have any of these amplifiers. We will keep this information up on our website in hopes of them becoming available in the future. We do still have some of the adapter cables available below.
