works fine without any caps (I'm lazy), so far anyway, heh, is it
hazardous to skip'em ? (I get a nice picture on my TV, so it seems to
work to me)

heh, yes, scince this is just for fun, the budget is quite limited =)

What voltage should I use then, the maximum or the minimum och in the
middle ? If I don't want it to get warm I guess that the current should
be as low as possible then ? (or would minimum current make the
oscillator to stop ?)
