Fast Download,all pages present,an excellent copy.THis enabled to find the origional part numbers and chase them up. The cartridge is proving difficult to find but at least I know the origional part number.Thanks to all.
;
The manual was as described. Complete with parts list and technical information. Fast delivery.
 ;
Simple and fast...
The diagrams are clear and legible; i have been a great help.
The site is very reliable and precise thanks.
;
Very easy site. Great service and quick release for download. Manuals are of good quality.

Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) for schematic diagram: Note: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise � � � � � � � specified. % : indicates tolerance. 2 : nonflammable resistor. A : B+ Line. B : B� Line. Power voltage is dc 14.4V and fed with regulated dc power supply from +12V and REM terminals. Voltage is dc with respect to ground under no-signal condition. Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.
