Product Description
So, you buy a really good radio or CD player, go to plug in your headphones, and there isn't a headphone jack! You find a line level jack, plug in your headphones, and they sound terrible. Sound familiar? Most good quality gear lacks an earphone output, or if there is one, it is woefully poor quality. We developed this kit to help us listen to our mixers, reverbs, voice recorders and other audio goodies. We took a pair of LM-386 250 mW audio amplifiers, added volume controls, power supply and a handy, switchable, high-cut filter. A common 1/4 stereo earphone jack is used for the output - assuring compatibility with all stereo headphones - and RCA phono jacks accept standard line level input signals. There's plenty of volume and of course, the Fi is quite Hi . Available in money saving kit form or fully wired and tested (model SHA1WT). Runs on 9 to 15 VDC. If you need an AC power supply, check out our AC125. Includes an attractive matching case measuring 5 W x 1 1/2 H x 5 1/4 D. (Did you know the leading manufacturer of high-end table radios recommends the SHA1C to all their customers?!)Reviews
Great soundI use this amplifier with Grundig S350 radio(line output) and Sennheiser HD280 headphone. They form a great music system; it seems to me that all of the three devices have quite a flat response.
Before you use it, you hvae to spend about an hour putting the components in the PCB and solding them. It took 20-30 hours to burn in. One thing I feel uncomfortable about is it is in lack of a battery compartment; if you want to install a 9v battery you have to unsrew two long screws and open the cover.
