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.
Xref:

2SB527 PS TO125 110 v 90v 5v 2A 10WT 50minHFE
Froms Towers Transistor Selector No freq. given.
There is also some crosses at
http://www.ee.washington.edu/circuit...rts/cross.html
Also my page.

I forgot to list the USA/Euro equivalant, also in the Towers book.
2n5180 and Euro BD140
Type in BD140 in findchips.com
Most people would just use the NTEreplacement.
I found a distributor who claims to sell this Towers
International Transistor Selector from 1977 ??
