good 6SN7 is almost lab tube, but has to be supplied with very high Anode voltage
(even higher PS voltage...) Lets say more than 300 of Va around -13V Ug and cca 10mA
to give awesome results. extremely linear...
Please take a look at the datas
Just little bit higher capacitances but there is no problem, just put the right value of input R or pot
which is 25K (22K) or less. persuming the stage before is low impedance source.
cheers

Thanks guys. It was a real pain to drill 67 holes of all sizes through that piece. It was a bigger pain to figure out all the sources of hum, but I finally got it dead quiet. It sounds great.
