I'd think that any PNP power xistor with an adequate voltage rating would
do - this is just a pass xistor wired as an EF isn't it?

I've identified a bad transistor in the power supply of an audio
component,
circa 1981. It's a 2SB527 PNP transistor... I had a bit of a look around
on
the net and didn't find any quick easy sources. This transistor's sole
function is to convert -26VDC coming off one side of a bridge rectifier
to -13 volts. [snip]
