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.
Precautions
1-4 Handling the optical pick-up
The laser diode in the optical pick up may suffer electrostatic breakdown because of potential static electricity from clothing and your body. The following method is recommended. (1) Place a conductive sheet on the work bench (The black sheet used for wrapping repair parts.) (2) Place the set on the conductive sheet so that the chassis is grounded to the sheet. (3) Place your hands on the conductive sheet(This gives them the same ground as the sheet.) (4) Remove the optical pick up block (5) Perform work on top of the conductive sheet. Be careful not to let your clothes or any other static sources to touch the unit. � Be sure to put on a wrist strap grounded to the sheet. � Be sure to lay a conductive sheet made of copper etc. Which is grounded to the table.

(6) Short the short terminal on the PCB, which is inside the Pick-Up ASS�Y, before replacing the PickUp. (The short terminal is shorted when the PickUp Ass�y is being lifted or moved.) (7) After replacing the Pick-up, open the short terminal on the PCB.
