This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

I do not have very much to say.
The price is quite covenient, delivery was better as promised (about 12 ours, against the specified 24 hours if I remember well), and the quality of the PDF is more than acceptable.
The Service Manual of Sansui R30 itself is also satisfactory: good graphic for schematics and layouts, simple and well structured.

Happy to find finally a schematic for this amplifier. The schematic is of good quality, the pcb layout is useless: all is black. Never the less, it is very easy to find the components on the board using the schematics.

Hard to find manual was ready the next day. Scans were very legible (including schematics). All the essential parts of the service manual were present (adjustment procedure, schematics, and parts list). It would have been nice if the rest of the manual was included (disassembly procedure, theory of operation, etc.).
TX-2100 ADJUSTMENT AND CONFIRMATION PROCEDURES 1
Idling current adjustment Before Idling adjustment, turn the trimming resistors R533 and R534 to counter clockwise. Connect the DC voltmeter to terminals P521 and P522. After turn POWER to ON, adjust the trimming resistors R533 and R534 so that the reading of voltmeter becomes 2.0 mV. After adjustment, attach the top cover. Confirm the voltage of points above after about five minutes. When less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV. When 7.0 mV to 9.0 mV, you are not necessary to adjust. When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV.

Confirmation of protection circuit 1. Confirmation of operation of speaker relay Confirm that the speaker relays turn ON approximate. 5 seconds after the power switch is turned ON. Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF. 2. Confirmation of DC detection circuit Press and hold down CD button, then press DIRECT TUNING button. After "TEST- " on the FL tube light on, press TAPE 1 button to set the unit to "TEST-1 00". Apply DC 1.5 to 3V to CD terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3V to CD terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..
