Safety is very important with this unit. When replacing the parts marked A , be sure to use only those designated parts. The designated resistors, diodes, transistors become hot in use. When replacing, be sure to secure them with a distance of more than 5 mm from the circuit board. In addition, they are banded together to avoid touching other wiring, recheck this point as well after repair.
The wiring of the primary side should be wound more than one and half times, then soldered.

1. Handle Assembly
When removing the parallel wire, it's convenient for connecting then again to do marking both on the wire side and socket side.
Remove 3 screws (5)
Remove 8 screws (8) and (9) fastening the speaker of Lch and Rch.
Fig. 12
Remove an E-ring (9) holding its assembly. Pull it off from the shaft.
4) Supply reel disc
Pull out the reel disc stopper (10) and pull out its disc from shaft
If you broke the stopper, you can use E-ring (REE-1200) in place of stopper.

5) Take-up reel disc Remove the counter belt (11). (Be careful not to stain the counter belt.) Pull out the reel disc stopper (12) and pull out its disc from shaft. 6) Motor Remove the main belt (13). (Be careful not to stain the main belt.)
Check the following items after cassette mechanism parts are replaced.
