 From a time nut pov this is probably less cleaning and more like infecting
with phase errors that drift along at the mercy of the temp. behaviour of
some unknown piece of ferrite.

(who is just winding the Amidon cores for the 5 and 15 MHz traps of his
5->10MHz doubler for the new Lucent.  1812 chokes have failed big time.)
