..."Dear tubemuseumusa,
I just want to thank you again for helping me get another matched tube after only ordering one by accident. They are by far my favorite 6AK5 tube I've tried to date! Much livelier than the (Mullard) M8161 tubes I was using, i.e. waaaay better mids and bass! I'm listening to some Ween on them right now as a matter of fact.
Thanks, Mark - mab1376"...

..." * Rp or plate resistance is the second most important parameter as it directly affects the output impedance of the preamp. Circuit designers are looking at Mu primarily, Rp next and we hardly care about Gm at all. Why then do most vendors measure Gm and Gm alone? Because most testers only measure Gm! No commercial tester ever measured Mu either (until the AMPLITREX AT1000 was introduced.) And even the Hickock, treasured for measuring Gm, doesn’t measure it meaningfully (due to current dependency), accurately (due to calibration difficulties) or consistently (due to internal circuit drift).'"...
