HornyAccording to the C3G data sheet at
http://www.mif.pg.gda.pl/homepages/frank/sheets/128/c/C3g.pdf
On page 7 max current is ~4ma
for .7 watt max disapation limit.
At 10mA the C3G will cook PDQ.With the ec8010 I think I looked at
the recommended operating point from
http://www.mif.pg.gda.pl/homepages/frank/sheets/117/e/EC8010.pdf
to get the 70V peak value
which is 125V/25mA/-1.175V bias.
At 140V/20mA/-1.5V bias
you can swing 90V peak which
at 20mA for 2.4K Rp is adequate.I'd prefer more headroom but
with your given parameters -
this will be as good as you can get.
IMHO Use either an IT or
cap coupled with grid choke for best results.DanL
