Hi Rage,
You have not executed this amp quite as I suggested. You need to fully bypass the Rk of the 12AX7 driver, to extend the amp's overall band width.
A single 20 uF film Rk cap, and a 0.68 across it, will roll off the top end. You could easily pick up four more db at 20 KHZ, if you would have done a complete and linear bypassing of the 12AX7's Rk as I detailed to you in numerous emails. Its important to do.
Grant Handley, aka GSH and Satin Patiently made the same exact error. Do that, and re measure and you will see, and you will hear it also !!
Cheers,
Jeff Medwin
