MIVAR T815LX It's a 14 Inches B/W portable television from MIVAR.
It has 12 Programs preselection with mechanic push buttons and a "big" tuning board with potentiometric channel tuning search.
In a typical VVC tuning system, a plurality of frequency-determining devices are used each of which has a plunger and a potentiometer associated therewith. This device produces a voltage used in tuning the receiver to any desired channel in the UHF or VHF band. The arrangement of the plunger arrays, and the indication of the channel to which each plunger will tune the receiver, has left much to be desired, from the standpoint of simplicity and convenience of operation.
The use of voltage-variable diode-capacitors, such as varactor diodes, permits the electronic tuning of radio receivers and television receivers by the use of DC control voltages; so that the tuning elements no longer need to be intimately associated with the tuner. Thus, the tuned circuits of the tv receivers may be located remotely from the devices used to provide the necessary DC tuning voltages. In addition, the compact size of the voltage-variable diode-capacitor tuning circuits makes it desirable to use such tuning circuits in many tv applications which formerly used mechanically adjusted variable capacitors or the like as the tuning elements.
This kind of tuning system was the type which in further models was featured electronically it's a television receiving apparatus including a presettable tuner having a plurality of plunger-actuated, frequency-determining, elements with which the operator can select desired VHF and UHF stations. To employ voltage-variable diode capacitors in pushbutton televisions sets , however, especially in multiband pushbutton television sets, a problem exists in providing a "memory," so that operation of a pushbutton will provide consistent tuning of the tv receiver to the station which is to be selected by that pushbutton.
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 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 ! ! !
