You need a paticular Triac listed in the thread - it's called an Alternistor and doesn't need snubbing - so you can remove the ceramic caps on your power switch. The power switch then acts like a gate trigger and you wire the Live in to the power switch. Then, from the power switch you connect a 100 Ohm resistor and then connect that to the Gate leg of the Alternistor.
You connect the main live coming into the unit to the Alternistor's MT2 leg.
Then you connect the transformer primary that would have come from the switch, into the MT1 leg of the Alternistor.
Hope that makes sense - don't try it unless your absolutely sure - also, be sure to get the insulated tab type Alternistor - means you dont have to isolate the metal tab from the chassis.
