[Premium-Rx] Tuning Knob's-past and present...

[Борис Никитин]

 Hi all groop members,

If anyone interested good illustration of classic, solid approach to tuning/control knob's "Know How" put to the Google search line (some few sites will appear)
russian "КРОТ" or "КРОТ-М" (KROT or KROT-M)  KROT that is special name and mean "Mole" ( unvisible animal normally spent time anderground activity...)
In KGB slang mean illegal agent...Was in use in KGB and Soviet Army in early 50s...Big Cold War "nukies" tension in that time...This days situation not ease also by the way...

One more, super hard design, that is Р-250  or Р-250М  (R-250, R250M) Widely used in Soviet Army, NAVY, in civil merchant fleet e.t.c.... Also in Cuba, Vietnam, Angola and other's countrys...

If you will drope it from third floor to the soil ground-nothing will happened...

Design same like Kalashnikov AK-47 or russian WW2 best tank T-34...

Those receivers is "Anchor Type Radio" and if you got your own experience to use them, your soul will never recognize modern plactic toys fith fucking menus...And multi function knobs and controls...Soul not brain!

In The West also some very good example of that type of radio..Some of them was installed in concrete floor in linkors- heavy battle ships.. In time of Real Era of Radio....
Much before Internet and mobil phones...
