Technics - Versterker SU 700 / Equalizer SH 8028 Hifi-set

I propose, from my personal collection, 2 items from the famous Japanese house TECHNICS.
Color black, recently cleaned, serviced, tested by an expert technician.

-TECHNICS SU 700 is an integrated stereo amplifier produced between 1986 and 1988. It is a classic component of Technics' "New Class A" era, appreciated for its reliability and the ability to deliver clean power for mid-sized domestic hi-fi systems.
Output power: 60 watts per channel into 8Ω (stereo)
Frequency response: 5 Hz to 90 kHz
Total Harmonic Distortion (THD): 0.04%
Damping factor: 50
Inputs: Phono (MM), CD, Tuner, Aux, Tape
Dimensions: 430 x 86 x 240 mm
Weight: About 5.3 kg
"New Class A" Design: Uses a biasing system aimed at eliminating the crossover distortion typical of Class B amplifiers, maintaining greater efficiency than pure Class A.
Audio Controls: Includes adjustments for Bass, Treble and Loudness, useful to improve the fullness of the sound at low volumes.
Speaker Compatibility: Supports speakers with impedance from 8Ω to 16Ω.

TECHNICS SH 8028 is a 7-band stereo analog graphic equalizer with LED illumination, produced between 1986 and 1988. It is appreciated for its reliability and the ability to customize audio without introducing digital artifacts.
Configuration: 2-channel stereo with 7 frequency bands per channel.
Control Bands: 63 Hz, 160 Hz, 400 Hz, 1 kHz, 2.5 kHz, 6.3 kHz and 16 kHz.
Adjustment Range: ±12 dB for each band.
Design: Sliders with integrated red LEDs, particularly striking in dimly lit environments.
Technical Specifications
Frequency Response: 5 Hz to 100 kHz.
Signal-to-Noise Ratio: 100 dB.
Total Harmonic Distortion (THD): Extremely low, 0.005%.
Dimensions: 430 mm x 86 mm x 193.5 mm.
Weight: 2.1 kg.
Connectivity and Features
Inputs/Outputs: Uses standard RCA connectors.
Tape Deck Loop: Includes dedicated connections for a cassette recorder, allowing equalization during both listening and recording.
Bypass Button: Allows you to bypass the equalization to hear the original flat signal.
Power: Often equipped with a service AC outlet (unswitched) on the back to power other Hi-Fi components.

I note for complete transparency 2 defects on the Equalizer.
- heat mark on the upper right side.
- absence of the cable clamp due to a break for replacement of the power cable.
Both defects do not affect at all the quality and the operation of the item.
