An externally hosted image should be here but it was not working when we last tested it.
Well I hope that worked.
Hi,
Not familiar with the 6N30, but most SRPP, especially if high bias, can drive nails.
+150V isn't a lot for a totem pole, and each section will only have ~75V across them, but that looks perfect from the specs.
Anode current is rated 40mA, so 20mA through each totem would probably be a right balance for Gm, noise and tube life.
Depending on the cathode voltage needed, consider using LED's for bias... their impedance and noise is low and you can lose the cathode cap.
As for Vp-p out, that depends on what THD you want to take it at. Likely enough to cook a SS amp input stage before you even hit 0.5%
Cheers!

Hi Jeff,
Cyrillic 6H30 == english 6N30, correct? TDSL seems to think so: http://tdsl.duncanamps.com/tubesearch2.php?TSD=6N30
