A good service manual with lots of info and a very fair price
;
Great value, good scan, just as expected, everything that you need.

Good scan, great price, but almost the same with the SV260 service manual.
;
This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.

This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.

3.1 Key Inputs
A key input becomes valid after 40 ms, to eliminate chatter. The ATT.THROUGH key input from OFF to ON becomes valid when the key is held pressed for 2 seconds.
Port 16 (SPRYH)(Pin16) is set to "L" 10 ms after ATT.THROUGH switching signal input, and relay is set to OFF. After another 30 ms, the INDICATOR port is processed. Port 31 (FMT)(Pin31) is set to "H," and muting is set to ON. Switching process is performed 100 ms after ATT.THROUGH switching signal input. When switching ATT THROUGH from ON to OFF: Data transfer to the DAC IC is performed 2 seconds after the key input. When switching ATT.THROUGH from OFF to ON: Port 2 (LD), port 3 (CLK), and port 4 (SRD) are fixed to "L" before DACVR (pin 13) is set to "L," 30 ms after relay becomes OFF. (See "6. DAC Volume Transfer."(P.49))
3.2 Switch inputs
The MODE switch (rotary switch) setting is read when the power is turned on. The switch operation with POWER ON is invalid. (See "7. WARNING."(P.50))
4. KEY PROCESSING (IC901)
4.1 ATT.THROUGH Switching
The ATT.THROUGH key input from ON to OFF becomes valid when the key is held pressed for 2 seconds. Any other key input during these 2 seconds is invalid. When switching from OFF to ON, the key input becomes valid at normal timing. After another 2 seconds, port 31 (FMT)(Pin31) is set to "L," and muting is set to OFF. After another 3 seconds, port 16 (SPRYH)(Pin16) is set to "H," and relay becomes OFF.
