• 1 Specifications for 03-1 to 03-5 are matched. If you
change D3-1 to 03-4, at the same time also change
FM VCO assembly. Likewise, if you change FM VCO
assembly, at the same time change 03-1 to 03-4. In
the case of both of the above mentioned, 03-1 to
03-4 parts are mounted on the newly ordered
FM VCO assembly ; use spare parts.
