Realistic / Radio Shack / Tandy / Archer
The discount came off before the price went on. But that's not the only powerful reason for buying the Realistic 2000 at the nationwide supermarket of sound.
75 watts per channel min. RMS at 8 ohms from 20-20,000 Hz, with no more than 0.25% total harmonic distortion. Under $500.00. Five More New-for-'77 Realistic Stereo Component Receivers
STA-16 119.95. STA-21 159.95; STA-52 199.95; STA-64 239.95; STA-235 399.95.
Built in our own factory, the Realistic STA-2000 will change quite a few notions about what an American company can do on its own. Even a 55-year-old American company.
Even a company that has been designing Realistic audio equipment for 22 years. Have another think if you've been thinking Realistic is great only in the middleweight division.
We've printed a big picture so you can clearly see what we mean. And if your notion of price is something like $5 per watt per channel, kindly remember that Realistic's is $3.33.
We may not always have a rug on the floor. But we have taken the "hi" out of hi-fi. And the Realistic 2000 is thundering proof-positive of our attitude about watts, quality, features, cost, and credibility.

Heathkit "Super-Amp"
The Heathkit AA-1640 is one powerful stereo amplifier- 200 watts, minimum RMS, per channel into 8 ohms with less than 0.1 % total harmonic distortion from 20-20,000 Hz.
That massive power virtually eliminates one of the most common forms of distortion- clipping. Driving low or medium-efficiency speakers (like acoustic suspension) to a moderate listening level may require 20 watts per channel. But a momentary musical peak twice as loud as the average level requires 10 dB more power- that's 200 watts per channel. If your amplifier can't deliver that much, the peak is "clipped" off. That destroys the music's dynamic range, making it sound dull, constricted and unrealistic. It also produces rough, raspy harmonics that can actually damage tweeters. You won't believe how good "unclipped" music can sound until you hear the AA-1640.
And what you don't hear sounds good, too.
Harmonic and intermodulation distortion are under 0.1 % at any power level from 0.25 watts to full power. We think that makes them absolutely inaudible. Hum and noise are also inaudible-
100 dB below full output. And you can enjoy all that quiet because the AA-1640 requires no fan. Even as a PA amplifier, its massive heat sinks need only normal ventilation.
Optional peak-responding meters monitor the power output directly in watts from 0.2 to 200 watts into 8 ohms and in decibels from-30 to +3 dB.
Expanded scales provide a highly-visible meter indication, even at low-power levels.
Special ballistic circuitry allows the meters to respond to peaks as short as a record click, making them extremely effective overload indicators.
It almost takes an engineer to appreciate the AA-1640's conservative, reliable de sign- direct-coupled, differential input amplifier, 16 output transistors (8 per channel) in parallel, quasi-complementary configuration, 12 pounds of diecast heat-sinking, a 25-pound power supply transformer, dissipation limiting, automatic thermal shutdown, and output compensation make it unconditionally stable with any load.
A special relay prevents power on/off thumps from reaching your speakers and protects them from DC and extremely low frequency AC. Speaker fuses are located in the primary feedback loop where they don't degrade bass clarity by lowering the damping factor-a Heath exclusive.
Its 1.5V input sensitivity is compatible with most stereo amplifiers.
But it doesn't take an engineer to hear how great the AA-1640 sounds. Its massive power and in credibly low distortion make a big difference. For the first time you'll hear how good your system really is-solid bass, free from "boom" and distinct, note for note...spacious, effortless mid range...realistic, high-definition treble. Combine that with the exciting dynamic range that rivals a live performance plus inaudible distortion and you've got sound that's nothing less than spectacular.
And when you compare performance and reliability, we think you'll agree that the price is spectacular, too-just $449.95 in easy-to-build kit form. The optional AAA-1640-1 meter accessory kit is just $69.95 and if you buy the amplifier and meters together you pay just $499.95-a savings of $19.95.

Form follows function.
At Yamaha, it's been that way since 1887, when we began making music by making the finest musical instruments in the world.
Today, the same advanced technology found in our musical instruments has made Yamaha a leader in state-of-the-art audio components.
For example, we engineered our innovative Orthodynamic HP-1 and HP-2 stereo headphones to give both the smooth, crisp highs of the best electrostatic headphones and the rich, clean bass of the best dynamic types at a surprisingly low price.
But it wasn't enough to make them the best sounding head phones ever heard. We consulted world-famous designer Mario Bellini to help us make them the most comfortable headphones ever worn. Because we knew if they were uncomfortable, you wouldn't put up with them.
That's why a soft strap distributes the feather-light weight of the HP-1 and HP-2 evenly over your head. Special foam ear pads form a supple, compliant seal. Height and angle are completely adjustable to your head.
Yamaha musical technology is also highlighted in our superlative TC-800GL and TC-800D stereo cassette decks, offering cassette convenience with performance rivaling that of some of the finest open reel decks.
To satisfy the most sophisticated recordist, both the TC-800GL and TC-800D offer incredibly low 0.06% wow-and flutter Dolby* Noise Reduction, and Variable Pitch Control.
(The TC-800GL can even be used for remote recording. But, if you don't like to do a lot of fiddling around, both models offer automatic convenience features like Auto Timer Start, Auto Stop, Auto Memory Rewind, and Auto Switching for CrO2 tape.
Also showing Mr. Bellini's touch, the functional wedge styling and stepped controls of these cassette decks give you easy control and visibility from any standing, sitting, or reclining position.
