I know this is an old thread but rather than start I new one thought I would ask here.

I have had an old triac lying about for quite a long time & never got round to rebuilding it, had a very small workshop & it got pushed into a corner & just stayed there lol
I am now looking at trying to do something with it & was wondering if the "Sprint 1220i controllers" were still the way to go or if maybe there was something else that may be better now.
