Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat.

Playback WS-48A (tape center part) in the FWD state and ad- just RV601 so that the frequency counter reading becomes 3,000Hz. Standard value : 2,9853,015Hz 2. Playback WS-48A (tape center part) in the REV state. Check that frequency counter reading is within 1.0% of the reading of step 1. Adjustment Location : 3-1. MECHANICAL ADJUSTMENTS PRECAUTION 1. Clean the following parts with a denatured-alcohol-moistened swab : playback headpinch roller capstanrubber belt 2. Demagnetize the playback head with a head demagnetizer. Do not use a magnetized screwdriver for the adjustments. 3. These measurement and adjustment should be performed with the rated power supply voltage (1.5 V) unless otherwise noted.
