About the preamp section of my integrated

A friend of mine helped me take a look inside my integrated. Just killing time-neither of us know anything about electronics. Still, it was a bit of a revelation. Very dirty! dust, cat fur, human hair, and even the sort of goo you imagine finding in a smokers lung. what I observed was that the pre-amp section was given very little room compared to the amp section- not a big suprise. But I was amazed by how messy and crowded the preamp section was by comparison to the amp section.I cant imagine how any techinician would be able to find anything in such a tangle of wires and with so little room to move about. My guestion is is this standard? enevitable? Or, are better made pre-amps to benefit from more room & orderly layout. What is proper?

Dust has remarkably little effect on solid state electronics, because the voltages are low and the circuits are high current low impedance. Tube electronics are a different matter, because of the high impedance high voltage circuitry. When the voltage gets really high, like for the CRT of a TV set, dust is attracted to the high voltage area, and can actually short it out so that the set won't operate.

Clean it out if that suits you, but don't try to do such a good job that you damage something.
