Technics Brochure Highlights
330 watts per channel, minimum RMS, both channels driven, at 4 or 8 ohms, from 20 - 20,000 Hz, with no more than 0.03% total harmonic distortion.
Triple push-pull, Darlington-connected, pure-complementary OCL power amplifier. First-stage differential amplifier employs single-packaged matched transistors and current-mirror loading.Constant-voltage power supply and four 18,000 uF filter capacitors maintain low distortion under high-amplitude transient conditions. 12 power-level LED's per channel (24 total) with 3-step range selector. Phono equalizer employs two M47LP transistors in current-mirror loaded differential stage, contributing to 97 dB phono S/N ratio (IHF A, re 10 mv). SEPP phono output stage. Phono overload of 300 mV (1 kHz, RMS) assures very wide dynamic range. Switchable phono resistance and capacitance for matching cartridge characteristics. Steep-slope (-12 dB/oct) high and low filters. Baxandall-type bass/midrange/treble controls plus "Acoustic Control." Midrange control center frequency variable between 250 Hz and 5 kHz. Two-way tape dubbing. 26-position true

attenuator volume control. Three-fold circuit and speaker protection. Automatic load impedance detector optimizes power transfer depending on speaker impedance. 8-gang variable tuning capacitor (5 for FM, 3 for AM). 4-pole MOS FET utilized in both RF and mixer stage. Local oscillator with FET buffer amp contributes to excellent spurious response rejection, wide dynamic range and high tolerance to strong input signals. 85 dB selectivity achieved with four 2-element "flat group delay" filters and double-tuned circuits in RF amplification stage. 19 and 38 kHz signal cancellors permit wide, flat frequency response in FM. Phase locked loop IC in FM MPX section for wideband, stable stereo separation. MPX hi-blend reduces noise on weak FM stereo signals. Ratio detector minimizes FM distortion, with high tolerance to overmodulated broadcast signals. In AM section, tuned RF amplification and triple-tuned coils in IF contribute to excellent selectivity. Main and remote speaker facilities. Jacks for adding future 4-channel FM and stereo AM adaptors. Pre-out/Main-in jacks.

Have some additional information about the Model SA-1000 Receiver? If so, I would sure appreciate it
if you would EMAIL
that to me. I'll add anything: What type of controls, specifications, number and type of AC outlets on the back...
anything!
One thing, though... if you see some info and you believe it is incorrect, that is certainly
possible. However, it does no good to tell me that "I don't think that's right".
You need to tell me the correct information to replace it with. For instance, if I have that
a particular model was available 1978-1979, and you believe that is wrong, then tell me the
exact correct range and your source of information, rather than "I had one of those in 1976". Otherwise, I can't
really change the database with any confidence.
The database currently contains "slots" for many AM Tuner, FM Tuner, Amplifier and Preamplifier specifications,
as well as many of the controls and features Technics has made available on these units. You can check the Sample Unit to see all of the database slots. You
might even be surprised at some of the slots that are available. However, if you come up with something that's not in the Technics Classics database, either a specification
or a feature, I can add it in just a few minutes, along with specific details about that feature for any model(s) you know of. Don't be shy - tell me!
These listings can only be as good as the information in them. With your help, they will improve over time. Please accept
my heartfelt thanks in advance for anything you can contribute.
