Trying to replace a burnt out transistor that I think was a regulator,
was attached to a heat sink so it was involved in power or
amplification I guess, anyway its located in a power supply and has
the code k1821 on it and a logo saying FC as well...and thats all. I
cant find any info on this thing, anyhelp is appreciated!!

It may be a 2SK821 FET. Do a Google search for the NTE web site and
crossreference it.
