download the manual in best pdf-quality.
Thank You !

I found this service manual to be complete in every detail except for troubleshooting charts. It would be helpful if it had a set of troubleshooting charts; however it is a very good manual otherwise and for the price it is very well worth it.
;
Complete manual included schematics layouts and alignment procedure, clear to read and magnify, extremely pleased with manual and owner manual . com's service

perfect, i am very satisfait for the réception of the sansui r-5l service manual, thank you very much

Tone control output. Super bass input. Must be driven at a low impedance. Connected to GND. Not connected. For the connection of RCH super bass compensation capacitors. Fader input. Must be driven at a low impedance. Fader output. The front and rear sides can be attenuated independently. GND. Serial data and clock input for control. Chip enable. Data is written in the internal latch when the chip enable signal goes "L" from "H", and each analog switch is activated. Data transfer is enabled at "H". Generates a 1/2VDD power source. A capacitor must be connected between VREF and GND as a troubleshooting against power ripples. Fader output. The front and rear sides can be attenuated independently. Fader input. Must be driven at a low impedance. For the connection of LCH super bass compensation capacitors. Not connected. Connected to GND. Super bass input. Must be driven at a low impedance. Tone control output. For the connection of capacitors that compensate for bass and treble in the tone control circuit.
