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.
