The network used in the SANSUI SP-70. How is it self-acting or stocking? The appearance may be dull or dirty. (Eiji Tamura)
Maintenance information: 2022.1.19 sound output confirmed
Accessories: none
Key Specifications: Attenuation 12dB/Oct Crossover Frequency 6000Hz 8Ω 97dB
It has been maintained in 2020. It is a network used for A5, A7, etc. Unlike channel dividers, it's easy to handle and sounds familiar to your ears (Yoichi Murakoshi)
Maintenance Information: 2020.9.19 Maintained (Replace input terminals with banana-compatible general-purpose products. Output terminal solder removed. Capacitor fixing and wiring insulation. ATT disassembly contact cleaning, contact grease application. Frequency characteristic measurement check (~ 42 kHz) was performed and the original capacitor was continued to be used for good results. (Check input/output waveform and balance, check sound output)
Accessories: None
Main specifications: Crossover 500Hz 8Ω W123 × H140 × D132mm 1.6kg
The price has been reduced! 2020/9/21 Selling price 75,000 yen maintained. It is a network used for A5, A7, etc. Unlike channel dividers, it is easy to handle and sounds familiar to your ears. Appearance is scratched, dull. Serial 30386, 30733 (Asaine Tomoho)

Maintained! This network is used for A5, A7, etc. Unlike channel dividers, it is easy to handle, and the sound is familiar to the ear. The exterior is dull over time and has small scratches (Sasaki Shota)
Maintenance Information: 2024.4.13 Maintained (frequency characteristic check, ATT cleaning, terminal cleaning)
Accessories: none
Main specifications: crossover 500 Hz 8 ohms W123 x H140 x D132 mm 1.6 kg
Maintained! It is a large input 2-way network used in ALTEC A5, etc. The high frequency attenuation attenuator can narrow down the driver to -16 dB with 10-stage switching in -2 dB steps. There is a feeling of use such as appearance, abrasion, dullness, etc. (Kobayashi Hitoshi)
Maintenance information: 2023.8.15 maintenance (characteristics/sound output check, ATT cleaning, terminal contact cleaning)
Accessories: none
Main specifications: 2-way network, 2 dB step/10 stage attenuator, allowable input, 250 W, crossover, 500 Hz, impedance 16 ohms, actual size W283 x H305 x D138 mm, approx. 8 kg
We have drastically reduced prices! 2021/10/24 sales price 148,000 yen 2015 maintenance product. It is a large input type 2-way network used for ALTEC A5 etc. The high frequency attenuation attenuator can narrow the driver to -16dB by 10-stage switching of -2dB steps. Even if you narrow down to -4dB, such as the old network N-500-F, it is a must-see for those who are noisy at high frequencies. I think that the balance is good around -10dB (Yasuto Koshihama)
Maintenance information: 2015.11.2 Maintained (terminal cleaning. ATT (SW) cleaning Swap some resistors and adjust the deviation of the left and right sides. The capacitor is restored to the original capacitor that remained inside by removing the film-con that had been replaced. Input/output waveform and balance check, sound output check. Check the frequency characteristics measurement (~42 kHz) and confirm that the capacitor can be used as it is)
