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!!!!
