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.

HOW TO HANDLE AN ANODE-CAP
� REMOVAL OF ANODE-CAP
NOTE : After removing the anode, short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon paint on the CRT.
1 Do not damage the surface of anode-caps with sharp shaped objects. 2 Do not press the rubber too hard so as not to damage the inside of anode-caps. A metal fitting called the shatter-hook terminal is built into the rubber. 3 Do not turn the foot of rubber over too hard. The shatter-hook terminal will stick out or damage the rubber.
