Iron - repairing power by force of lungs.

       Blow, and everything will be ...

... I've got work to low-frequency amplifier, "Radio
U-101, "1986 edition. In recent years it has become
too much "pop" the volume control. Stereo balance knob
also began to "play pranks." I must say that the appearance of
faults of this kind I detsel surprised, since I was
known that this device was used variables
resistors made by thick-film integrated
technologies, such as the one applied in the production of
hybrid microcircuits. According to the magazine "Radio"
mid-80's, such controls is virtually permanent. But patience
finally snapped, and I climbed inside the amplifier. M-da-a,
operation for 11 years, even in the same hands, but not
anywhere, and at school, gave his "fruit" ... Amplifier
repeatedly visited and discotheques in the halls, and the voice 
of "street" and adopted over the years "inside" is not only the 
usual dust, but also one that that is formed by sanding parquet 
flooring. Construction of film peremennikov not too different 
from normal. Housing only another form, but conductive horseshoe

lighter in color and it seems brilliant. It is amazing, but it 
is not visible traces of the contact slider. And on that I drew

Note: Resistor is working without any lubrication (in the usual
potentiometer with carbon conductive layer that is smeared
grease). Became clear that the clumsy methods
recovery of carbon resistors (cleaning, shading with graphite 
and A new lubricant) here will not work. Until now, I can not 
give myself report that gave me the crazy idea just to blow off

lie inside the resistor dust ... Probably still lack
lubrication, and - as a consequence - the lack of adhesion of 
dirt, which breath does not remove. Typing in the lungs a 
little more air, I loudly, with cotton ("ugh!") dramatically 
gasped for RADIODETAL ... The results were striking. The 
regulator has earned as brand new, and continues to work! 
"Eternity" quality factor Baltic Soviet product was confirmed. 
Here such here pies. And do not seek to replace the radio 
market, do not dismantle wireless set, no need to take over the 
soldering iron. As see, and inanimate nature, it happens, the 
wounds will heal, if they blow ...
