Works, thanks!

I have already started playing around with your example, so here's a 
first question regarding the input voltage. You first set up the input 
voltage as "vin nin 0 sin f=1k amplitude=20 ac 1".
- As far as I can tell, this gives 1 kHz sine with an amplitudie of +/- 
20 V. What ist the "ac 1" part good for?
- Later on, you apply different DC voltages to the input (".dc vin -24 
24 4") --> does that delete the previous configuration of the input 
voltage? Where / how would I find this information in the Wiki manual?
- Then you seem to apply an AC signal ranging from 1 Hz to 1 MHz to the 
input (".ac 1 1e6 * 10") --> how does Gnucap know that this AC sweep 
should be applied to the input? Where / how would I find this 
information in the Wiki manual?
