Re: Looking to Cross ref a Diac & Triac set

Hello again, I have a circuit for an electronic Variac that uses a Diac
and Triac to control the output. It looks like a glorified dimmer
circuit. Anyways it uses part # MAC2-4 for the triac and MPT-28 for the
trigger diode (diac). I haven't been able to cross reference these
puppies on the net. I hav checked the usual sources, but came up empty.

They're ancient, that'll be the problem !
