I'm looking to replace some toasted-looking transistors in a Musical Fidelity B200 but am having trouble sourcing two of the small transistors. Here's the schematic:

An externally hosted image should be here but it was not working when we last tested it.


The offenders are TR1 through TR4, but I can easily find the TIP32C and TIP31C. The ones I'm asking about are:

TR2 - BC416C
TR4 - BC414C

Here's a shot of TR4. TR2 is the exact same package.

An externally hosted image should be here but it was not working when we last tested it.


Any help would be greatly appreciated.

Well, seeing as how they are uses as a CCS, they could probably be replaced with any small signal part such as a BC850 or BC856, just make sure the pins are the same. If you use a fast transistor, you might include small cap(100pf) across collector to emitter to prevent oscillations.
