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.).

The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.

11. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000 Hz ± 5 Hz (FWD). 12. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 8 kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 13. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8 (Lch), TP9 (Rch) Method : Play back the 315 Hz and 8 kHz signals of the test tape and check that the output ratio of the 8 kHz signal with respect to that of the 315 Hz signal is 0 dB ± 5 dB. 14. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8 (Lch), TP9 (Rch) Method : Play back the test tape and check that the output level of the test point is 110 mV ± 3 dB. 15. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8 (Lch), TP9 (Rch) � Input signal : 1 kHz / 8 kHz (LINE IN) (-20VU) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes 0 dB (10 mV). Record and play back the 1 kHz and 8 kHz signals and adjust SFRs so that the output of the 8 kHz signals becomes 0 dB ± 1 dB with respect to that of the 1 kHz signal. 16. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8 (Lch), TP9 (Rch) � Input signal : 1 kHz (LINE IN) (0VU) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0 dB (100 mV). Record and play back the 1 kHz signals and check that the output is -1 dB ± 3.5 dB.
