Introduction to Mechanical Tuners:
TURRET TUNER:
The turret tuner or drum type tuner is so named since coils for several channels are accumulated on a slotted drum type structure that k rotated through the channel selector. The tuned circuits are accumulated on separate strips for each channel that are clipped into the turret. The coils needed are selected through rotating the turret so preserving the shortest probable length of connections. Every strip contains coils for RF amplifier, local oscillator and mixer for a single channel. The schematic of a VHF turret tuner displayed in diagram demonstrates the way in which a coil-strip on the drum creates connections with the rest of the circuit.
WAFER OR INCREMENTAL TUNER:
This tuner uses a wafer switch type construction in which a tier of wafer switches allows selection of the appropriate mixer, RF, and oscillator coils. The coils are generally accumulated around the outer rim of the switch along with a few turns of wire for the lower channels and increasingly decreasing for the higher channels. To connect one set of RF The wafer switch is rotated, mixer and oscillator coils for every channel diagram displays schematic of VHF tuner-wafer switches. Note: the coils for oscillator, RF amplifier, and mixer stages are on separate wafer switches that ganged on a common shaft. The oscillator coils are all the time on the front section for convenience of adjusting the inductance to set the frequency.
The wafer type tuners are also termed as incremental tuners since the change of channel is accomplished through an increasing shorting of sections of the total inductance. 2 to 6 individual coils are connected in series and are increasingly shorted out for channels. 7 to 11 only single rum or half a turn is enough for tuning, for channels.
Channel I is not allocated for TV broadcasting anymore and this position on the selector switch is usually employed to start the UHF A tune. The current version of tuner wafer construction uses a printed I circuit wafer. In this technique all coils for higher channels are replaced through printed circuit inductances. This technique has the benefits of better reliability, better uniformity of alignment and lower cost.
