Well done on getting it going and it would be great to see a circuit diagram. However, one thing concerns me slightly:
I believe a snubber network is primarily to prevent the triac being damaged by high voltage ringing when it switches off. It is not sufficient to provide proper filtering of electromagnetic interference - for this you need a series inductor at least, as contained in light dimmers. You might not get interference on FM radio or TV, but you are very likely to hear it in MW or LW transmissons and it may become apparent on FM and TV when the wanted signal is weak.
