I'm running some tests on a selection of circuits supplied with this
version of spice I'm currently trying out. I've noticed that when I
run a TA on a 7Mhz Colpitts oscillator with a 1v supply rail WRT GND
(this is the specified value in the schematic although it seems
*bloody* low to me) I get a steadily increasing output signal sine
wave of well over 13volts (and it's *still* climbing by the time I get
fed up watching it). How can this possibly be right? It's hardly
likely in the real world (even with my scope:-)).
