I own this small amplifier and use it with the matching tuner (TA102) in a small personal office for radio listening and PC sound system. The SA102 provides bigger systems features like three selectable RCA input with one for phono RIAA, balance and tone buttons, earphone plug.
The schématic is classic for seventies, and easy to repair (I replaced a pair of blown power transistors)
Good and clear sound, nice front panel. Inexpensive

Why you will want to start buying Realistic micro amps from the silver era. These unit are dirt cheap 5.00 or even at one dollar. They don’t use speaker wire connectors they have rca jack for the speaker out. Now look as this thing as a pre amp phono stage with a switch to go from moving magnet or moving coil really for a dollar plus tone controls balance plus now a selector box to hook up three components to your stereo or amp it amazes me when I see audiophile guys walk right by these units and don’t buy them the phono stage is as good as any 100 dollars phono pre amp available today and you have the MC setting. Hook up the speaker output rca jacks to inputs of you main stereo and your good. Now select phono and use your volume control for variable input you can over drive it so adjusts to volume from your mini pre amp stereo all the SA units have this feature. Best phono pre amp for 5 dollars and under. I buy everyone I find.

re: SA-102

These amps (SA102, SA150, SA155) rock! Don't let the conservative power figures (1.8w/channel) throw you. They're based on an LA4440 chip which can deliver up to 6 watts/channel. The 1.8 Watt figure is how it's rated to keep distortion under 1%.

Most people don't realize how loud 1.8 watts can really get with efficient speakers. That's 'cause the curve (power output versus actual loudness) isn't linear. To double loudness requires something like eight times the power, or something like that (I forget the math, but I do remember the general manner in which it works).

Paired with a set of decent speakers, they'll fill a room just fine. Okay, so it won't shake the rafters. If that's your goal, you shouldn't even honestly be looking at mini-amps in the first place. But if you want something compact, efficient, and boasting some pretty decent features... this is it. Balance and tone controls, stereo/mono switch, a selectable magnetic/ceramic phono input plus two line level inputs, a tape-out connection, a headphone jack, and (in the SA155), a third line input (1/8" stereo plug) on the front panel (plug in a Walkman, MP3 player, etc) and it'll automatically switch over.

And you can find 'em all day long on eBay for <$40...... under $30 sometimes if you look around a little.
