how did you hone in on 2-8 khz?
i have only two trusted sources for tested tubes..
Andy at Vintage Tube for non Russian
Roger at RAM for everything...
probably two of the most knowledgeable and reputable testers, backers and sellers. Roger in particular ascomputerized his proprietary test parameters...consults to tube manufacturers, builds his own line of tue gear ( music reference )......
just looked over this rather extensive mod...wow..cool. What does Dan recommend ????
my guess is might benefit from dampers ( i like ARC ), and seperate HRS bases for each box, likely a damper block on the 105.... and certainly experimenting with a dedicated circuit / condtioning....
i would start w output, work backwards....
have fun...
