      From: phil_a@tpg.com.au              "Big Bad Bob"       >       > OK I ran the experiment myself. Test circuit used 120VAC to 24VCT       > transformer (rated at 2A) with 10 ohm resistor in series with the primary.              ** Change that resistor to 1 ohm and try again.              Cos you went and put a resistor in series with the primary of similar value       to the primary's own resistance - which has the effect of dramatically       reducing the peak current of a worst case surge.              Folk regularly use NTC thermistors for that exact purpose !!!!!              Then try more transformers - particularly those of a few hundred VA and       toroidal types.              You will need a resistor about 0.1 to 0.5 ohms with plenty of power rating.              Fuckhead.                     ....
