[R-390] 26Z5W replacement

There used to be an excellent article about using 12BW4's at this link:

http://www.xmission.com/~cwest/Reference/12BW4Mod.pdf

However, that link is now "404".  Does anyone have a copy of that article?
I bought some 12BW4's with the express purpose of trying that mod, but I
don't think I kept a copy of the article  :(

Thanks,

Barry - N4BUQ

Has anyone tried rewiring the rectifier scoket and
using another rectifier tube in its place instead of
going solid state and wiring in a resistor?
