    Hello! I'm actually looking to purchase a very simple audio amplifier with these specifications:

    - Consistent gain of 20 dB across high and low amplitude input signals
    - Output of up to roughly ±10 V for a 50 Ω load (earphones)
    - Cheap

    If it can give a higher output, that's great, and extra functionality (e.g., other gain options) are welcome!

    I've been happy with my Radio Shack " Mini audio amp" 277-1008C, 200mW, 100-10kHz, 5k in, 1mV, 16Ω speaker & jack, 9V battery & jack, about $14. Uses 386 IC with one pre-amp stage.

    Thanks for the replies. For a 10V output over a 50 Ω load, I believe I'll need something that can pump out 2 W or higher. Some of the items on the Firestone Audio site look promising!
