    If you showed us the circuit diagram and application we may be able to suggest substitutions.

    This is for power Amplifier and I am afraid that I don't have a circuit diagram. Can you please advise any thing with this info

    Do you have a make and model number, a photo or specs of your power amp?

    Where is you local market? If it is not the US or Europe, most of us are unlikely to have any relevant first hand knowledge of what is available in your local market. In most of the world there are very few storefront shops where electronic components are available. Electronic supplies are ordered online and shipped to your destination. Depending on type and quantity it might not be unusual to pay more for shipping than the components are worth.

    Why look for a substitute when there are plenty of the EXACT part numbers you are looking for on ebay.
    You can get a complete replacement set (2x NPN and 2x PNP here and they ship globally except Italy).

    ...or here for 5 of each part number ($19.99 including global shipping)

    All you have to do is google "xxxxxx equivalent", where 'xxxxxx' is the part number of the transistor you're trying to replace. Either that, or just find a transistor with the same voltage/current and switching specs.

    These are used as output transistors in an audio push/pull stage and should be bought as a matched pair.
