 ;
The manual was of good quality with high resolution schematic diagrams.
;
The manual was very clear and contained all the information I was looking for. My dishwasher is working again because of this servicemanual!
;
Quality scan, great manual. I solved my problem with this manual.
 ;
The AKAI 1720 model reel to reel tape recorder described in this Manual is quite an old unit - circa late 1960's. As a consequence, the description of the mechanical details - and adjustments thereof - is quite critical. The manual does this quite well. The schematics are also well presented and have detailed PCB overlays. Probably the only negative is that some half-tone detail has been lost from the original manual as it has been scanned in simple B&W.
;
Perfect source for service manuals: fast and professional transaction; high quality, perfect readable and largely scaleable PDF; complete schemes, diagrams and spare part list. Tnx a lot, cu again!!!!

RP-231 (REC/PB AMP) SCHEMATIC DIAGRAM � Ref. No.: RP-231 Board; 1,000 Series �
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)
� For printed wiring boards. � : Pattern from the side which enables seeing. � + : Through hole. Caution : Pattern face side: (Conductor Side)
Parts on the pattern face side seen from the pattern face are indicated. Pattern face side: parts on the parts face side seen (Component Side) from the parts face are indicated.
� For schematic diagrams. � Caution when replacing chip parts. New parts must be attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, because it is damaged by the heat. � All resistor are in ohms, 1/4W unless otherwise noted. Chip resistor are 1/10W unless otherwise noted. k�: 1000�, M�, : 1000k�. � All capacitors are in µF unless otherwise noted. pF : µ µF. 50V or less are not indicated except for electrolytics and tantalums. � : panel designation. � : internal component. � : B+ Line. � : B� Line. � : IN/OUT direction of (+,�) B LINE. � Circled numbers refer to waveforms. � Readings are taken with a PAL color-bar signal input. � Voltage are dc between ground and measurement points. � Readings are taken with a digital multimeter (DC10M�). � Voltage variations may be noted due to normal production tolerances.
When indicating parts by reference number, please include the board name.
