Ok, how about this problem.  I have two Radio S* PA amps, 30 or so Watts,
cheap little things, that have both output trannys shorted.  Clearly
marked on the packages is "D 1046", which I assume to mean 2SD1046, but
there seems to be no crossreference anywhere that lists the D or 2SD type.
By anywhere I mean the Moto power tranny book and Radio S*'s own reference.
They're almost certainly NPNs, and they drive an output xfrmr (I assume
center-tapped since they're both NPNs) with a 40V or so power supply.
They're in what looks like a TO 220 case on steroids ;-).

Anybody got any ideas?  A local little-league will surely appreciate it!
