John,
Could I interest you in some "Prime" Florida Real Estate? You can't  
miss!

A very famous,  articulate,well rounded and knowledgeable 
"audiophile" friend of mine tells  me the same thing over and over again: 
"Just because YOU can't hear it  doesn't mean it's not there"

(for those among us who might not know who  the above person is, I'll give 
you a hint: he's not a Ham, and lives  somewhere in Delaware County,Pa)

Yes, I too wonder what motivates some  people to pay exhorbitant 
"audiophool" 
prices for some tubes. I guess it's  what they "(read) think they hear or 
would like to, let alone bragging  rights, etc.

What you really want to look out for in the 12AX7 hi-mu dual  triode line 
is 
a "Telefunken". They're supposed to be the premium tubes of  their genre. 
I've swapped out the various brands with a dual gettered 1960  production 
Telefunken and quite frankly, couldn't tell much of a difference,  though 
there were nuances........ Is it worth it? Let your wallet be your  judge.

Joe  you are giving Delaware County a bad name. 
 
If it sounds good and sounds accurate why bother with the measurements.  
Enjoy it.
 
If I ever get my train back on the tracks I will be willing to do a blind  
test to see what differences I can hear between caps and tubes.
 
Would you please ask those bats to keep the noise down so I can  
concentrate.  Well into my 30's i could hear past 23K.  A blessing?  Sometimes i think 
not. I spent a lot on HiFi and a lot bit my ears.
 
I'm 61 now and can still hear the horizontal Osc, sometimes louder than the 
 audio from the TV.
