Elias looked up the datasheets. and B778 (PNP) were a classic complementary pair, used for driving the larger output transistors in high-fidelity amps. They were robust, handling significant current for their size. The D2390 and B1560 were their modern spiritual successors. They had a slightly higher voltage rating and a robust plastic casing.
Power amplifiers contain lethal voltages. If you are not experienced, consult a professional technician.
Finding the exact original part can be difficult, but you have many equivalent options. The key to a successful equivalent is to use a with equal or better specifications. If you upgrade the NPN, you must upgrade the PNP with a matching counterpart.
