[R-390] Alternative to IERC tube shields?

[rbethman]

I pointed our friend Osamu, in Japan, to the Evil Place.

There was a full set going for the price of the Audiophool Single.  They 
were specifically for R-390A or audio amplifier.

The set finally went for $51.  Considering that he doesn't have access 
to our hamfests, if it was him that took the bid, then he made out just 
fine.

I have more than enough for my R-390A.  My SP-600 has gotten a "few", 
the remainder are going bare!  It sits in a rack with neither a top nor 
a bottom.  There is enough room in the rack for the R-390A when it comes 
off the bench, and still have space for the power supply and 4-1000A 
amplifier. 

Oh yeah!  I forgot to mention that an R-42 reproducer is the top element 
in the rack!  Switchable between the two different receivers!
