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.

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.
 Founded in 1945 by Mr. Carlo Vichi class of 1923, The activity started in 1945 - in Milano,  Via  Ugo Tommei 5 street with fab
Founded in 1945 by Mr. Carlo Vichi class of 1923, The activity started in 1945 - in Milano,  Via  Ugo Tommei 5 street with fab
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 ! ! !
