Most of the problems with el-cheapo dimmers in those $40 halogen
lamps can be solved by:

1. Adding a resistor in series with the triac gate, to get rid of
   potentiometer backlash.

2. Getting the diac trigger voltage through a double RC network,
   to obtain zero through 360 degrees of conduction.

3. Adding a pi (CLC) network to reduce RFI.

Way back in the '70s, RCA had schematics and values for these in
one of their triac data books. They also mentioned:

4. Connecting a snubber network across the triac (MT1 - MT2) for
   dV/dt control of inductive loads.

My old RCA databooks are long gone.  Can anybody look thses up and post
the values?
