The MIVAR MOD: 16" 82 C4 is A portable 16 inches (42CM) color (very HEAVY) television from MIVAR a still alive Television constructor in Italy.
Was First model series compact Color portable set from MIVAR.
This set has 2 antennas mounted on top for VHF AND UHF Channels analog Broadcast.
It has 16 Programs and VST search tuning (SGS CHIPSET) RT12-32 and remote.
Each channel band can be explored at one time, when a program is identified the search will stop automatically then AFC is performed and the user has the choice to store that tuned channel in the current program position and television receiver includes a voltage controlled tuner having a nonlinear tuning voltage-versus-frequency characteristic, tuning voltage means for generating a tuning voltage for the tuner and memory means storing reference tuning information, first increment tuning information related to the slope of the characteristic at a base channel and second increment tuning information related to the slope of the slope of the tuning characteristic at each channel position. The memory means supply the tuning informations to accumulator means which generate therefrom the nominal tuning information and slope factor for the selected channel.Typical tuners using varactor-type diodes require a substantial range of capacitance change of the varactor diode to cover the frequency range of interest. The capacitance characteristic of typical varactor diodes, however, is not linear with respect to the applied bias voltage. While this problem is not unduly limiting with respect to the applied tuning bias voltage, the automatic frequency control (AFC) of the tuner is deleteriously affected. The AFC circuit provides a given correction voltage for a given frequency deviation from the proper intermediate frequency. Since the varactor diode capacitance characteristic is non-linear, however, a given AFC correction voltage provides a differing amount of correction depending upon the bias voltage or channel received thereby resulting in a varying AFC pull-in range. For example, if the proper pull-in range is provided at the low-frequency channels in the band of interest, the pull-in range at the high frequency channels becomes insufficient. Conversely, if the proper or desired pull-in range is provided for the high frequency channels, the pull-in range at the low frequency channels becomes excessive which can lead to such deleterious effect as locking onto the associated sound carrier, locking onto adjacent channel carriers and similar problems.
First tuning control type with Infrared remote receiver, previous models were with ultrasonic types but the set doesn't use a Microcomputer device like others.
Featuring first time the use of the PHILIPS TDA3560,It combines all functions required for the identificationand demodulation of PAL signals. Furthermore it contains a luminance amplifier, an RGB-matrix and amplifier.
The television set here shown was introducing a circuit arrangement for generating a sawtooth deflection current through a line deflection coil in an image display apparatus, which circuit arrangement comprises a deflection network including the deflection coil, a trace capacitor and a retrace capacitor and a first diode through which the deflection current flows during part of the trace interval whilst during the remainder of the trace interval this current flows through a second diode and a controllable switch, which switch and which second diode are connected in parallel with the first diode, the circuit arrangement further comprising an inductive element which is connected to the switch and is coupled to the deflection network via a third diode, and a transformer which has a core of a magnetic material and a winding of which is coupled, in series with a capacitor, to the deflection network.
Such a circuit arrangement is described in "IEEE Transactions on Broadcast and Television Receivers," August 1972, volume BTR-18, Nr. 3, pages 177 to 182, and is a combination of a line deflection circuit and a switched-mode supply voltage stabilizing circuit, the controllable switch being used to perform both the said functions. This known circuit arrangement has the advantage that it can be fed with an unstabilised supply voltage and is capable of supplying a satisfactorily stabilized deflection current, a stabilized high voltage and, if desired, auxiliary voltages, the stabilization being obtained by control of the conduction time of the swtich.
The plastic used for the cabinet is of very good quality grade, higly better than other bigger brand type quality therefore made with highly stable heavy plastic material.
These sets were sold at fair price and they did last very long.
In 1982 and in previous times MIVAR society name was Radio VAR then converted definitely to MIVAR.
In ancient times MIVAR was even a radios constructor, then the interest dropped quickly to only television manufacturing.
It's made by MIVAR an Italian Brand no more active since 20/12/2013.
MIVAR is a Factory site in the near of Milan (italy) in a Industrial city conglomerate called Abbiate Grasso.
1945 - Milan, Via Ugo Tommei 5: Begin the activity assembling small radios.
1950 - Via Curtatone 12: developed with the construction of more direct major radio components fabricants.
1956 - 13 Street Strigelli: industrial production is manily targeted to first radio devices with frequency modulation (FM).
1958 - Via P. 30 Jordanians: TV become a reality, the industries is doubling his ACTIVITY, always in Milan, we build the first "real" plant with 400 employees.
1963 - Abbiategrasso, Via Dante 45: in the wake of decentralization and the rampant success of the television, building a facility that will become important in place 800 employees occupying between 1968-70.
1990 - Abbiategrasso Canal towpath: aware of the physiological importance that television plays in society? Modern, rich expertise and resources, we began construction of a factory area of 120,000 m? which covered 30.00o , for the viabilit with parking spaces and 60,000 park trees.
Today's activity is oriented in virtual production of LCD crap but with very low market penetration due to "unfair" asian competitors presence and a local governement which don't care about.
(You call it global market, I call it WORLD DESTRUCTION combined toghether with mass Afro scum crap Immigration (EUROPEAN INVASION) to obtain destruction on a large scale in all places and to help more and better the loose of all OUR workplaces and firms , lives, people).
“If our buildings, our highways, and our railroads should be wrecked, we could rebuild them.
If our cities should be destroyed, out of the very ruins we could erect newer and greater ones.
Even if our armed might should be crushed, we could rear sons who would redeem our power.
Anyway Obsolete Technology Tellye will show even this model as a Time machine which looses nothing of the good tellyes ! ! !
