ALIGNMENT CTUNER CL-16333 The RF Amp. and Mixer culcuits of this tuner are pre-aligned at the factory and normally do not require adjust- ment. However, if tuner is definitely known to be out of alignment, it will-be necessary to remove the tuner and use extended leads for B+ and the filament supply. Remove the oscillator tube V301 and set the fine tuning control to the center of Its range. DUMMY ANTENNA Two 125S carbon res.

Picture should re- main In synchronization. Turn channel switch to another channel and then back to the original channel. Normally, the picture should be out of synchronization. Turn the control clockwise and the picture should slowly begin to synchronize and finally lock-In. This should occur when the control Is approximately 90 from the extreme counter- clockwise position. The picture should remain In synchro- nization for another 90 In the clockwise direction of the control. At the extreme clockwise position the picture should again drop out of synchronization and
