19、IGNMENT The sound IF section must be properly aligned before attempting oscillator alignment. Replace the oscillator tube (V3) in its socket. Since incremental inductances are connected in series with the tuned circuits of channels 8, 10, and 12 to form tuned circuits for channels 1, 9, and 11, the

20、order of alignment is important. It is essential that the higher of the paired channels, (7 and 8, 9 and 10, 11 and 12) be aligned first. The signal generator output lead should be terminated with its characteristic impedance, usually 50 ohms. Set the fine tuning control to the mid-position of its r
