After trying a pair, the most elegant modification which eliminates the 
26Z5's is using the Sigmapert replacements.  Therre are many good 
reasons to remove the 26Z5 firebottles, most are covered in the R390A 
video.

I'm installing an owner procured set of the Sigmapert replacements in 
the present radio I'm working on and took the opportunity to read the 
theory of operation and design objectives.  He addresses the 
shortcomings of both the original tubes and their diode du jour 
replacements.  I'm going to strongly recommend the Sigmapert from here 
out.
