Good workmanship and careful adherence to instructions are necessary in the building and operating of the 6N2 Meter Variable Frequency Oscillator. Although the design of this VFO was carried out with the objective of reducing the number of critical circuits to a minimum and making assembly simple, the capacitor and inductor values of the tuned circuit components were necessarily chosen with a given parts layout; therefore, the builder should duplicate the layout shown in the illustrations and described in this test. Circuits should be checked against the schematic diagram during the several steps of assembly. Much time and effort may be saved by finding an error or deviation from the illustrated layout before the unit is completed. Read each step through before commencing the operation.
