The simplest way to test the KNB2 is to rub a screwdriver across Q21 - the
RF Preamplifier- a metal case transistor which is visible when the K2 top is
removed. That will generate the kind of noise that it is supposed to
suppress.

Search the archives with keywords "q21 noise" and you will find more about
this test.


Good luck!
