However, because the sam takes so little from the 12V supply they also tend to burn out the 12V zener as it has to sink too much of the excess current, so the 12V series resistor often has to be changed for a higher value. Apart from that, they are very much the same. hth -- Nev - no longer at [EMAIL PROTECTED] and getting no spam at all (yet) Webpage under construction at www,nfy53,demon,co,uk also hiding on ICQ
