C2570 or C2498 Transistor needed

I blew a C2570 transistor and have failed to find a suitable replacement. The circuit requires either a C2570 or a C2498. maybe a SK9139? Anyone know which is tougher? Any others may work?
The circuit I am working on is a Ramsey FM10 Stereo transmitter. Thanks!

It is probably a 2SC2570 you are looking for. Here are the specs for it:
