[AMRadio] Testing tubes

[DOXEMF at aol.com]

John,
Now that was what I wished to say, LOL!!
I can't agree more with your observations and technique.
It also explains my liking medium Mu 12AU7 based circuits
over AX7's.
As long as there is enough gain to properly drive the following
stage hi Mu tubes are not really needed.
I'm looking forward to getting the test set together again and looking at 
some of this under controlled conditions and doing
proper documentation. 
I will not limit myself just to audio tubes but plan on being
able to fire up just about any tube and run curves out.

Anybody an A/D software GURU so the testing can be
automated? Guess the SOFIA unit is no longer in production.
Thanks,
Bill KB3DKS
