[R-390] Starting the tear down

[James A. (Andy) Moorer]

I only have one worry about dousing a boatanchor - mind you, I have done 
many dozens this way and I've never had a problem that I could trace 
back to a bath. My concern is that the ferrite material in the coils is 
porous. I worry that maybe some 409 could get in it and maybe not ever 
get washed away by the gallons of distilled water I slosh over the unit. 
Maybe, a decade later, it would morph into something nasty and crack the 
cores or freeze them or something. I have taken to taping over the ends 
of the coils to maybe keep most of the 409 out. I take them off for the 
final distilled water bath, after I think all the 409 is gone. 
Everything is squeaky clean, and my conscience has been sufficiently 
deceived to carry on.

Again, I don't know that it does anything bad, but what you don't know 
can sometimes come back to bite you in the bohunk.
