The MPSU57 can be replaced with NTE189 or NTE50 (TO-202 package). NTE50
can be bought at frys.com. I haven't found a source for the NTE49's,
but Bob Roberts has both the MPSU07 and MPSU57 listed on his parts page
(including the TO-202 package versions) so you may want to email him.
They're not cheap.
