Can you make an amplifier?

Hello friends of the forum this time I have a doubt I have a transistor of the old 2SC1664 I would like to find more information about that transistor since it does not appear much my question is that if you can make an amplifier with that transistor from already thank you very much for your cooperation and time regards

If you can and this is the one that replaces it but it is discontinued, both the replacement and the original.

Ok I understand then there is no diagram which I can use to not throw it away

What kind of amplifier do you want to do .. ???
Because saying that you have a transistor to build an amplifier is like saying that you have a tire and want to build a car. 4 tires are needed.
An amplifier could have more than one power transistor and you will not find the original or replacement.
It is much more practical to use an amplifier IC than to do it with transistors, especially when you have little experience.

If Nelson there are diagrams but that was not what you asked, you did not ask for a circuit, you asked if you could not arm an amplifier with that transistor and you also did not specify if you had more.

Hello friend Nelson, if you have 4 equal transistors you would have to arm the quasi complementary driver circuit and if you have 2 2SC1664 transistors and the complementary ones the driver circuit is complementary. Transistorized sound amplifiers have superiority over integrated "power, sound quality, repair costs etc ... On the Internet you will find a lot of information about it.

This circuit works well with +/- 40V minimum and with more voltage and more transistors for more power by modifying a few components.
here in the Colombian Caribbean coast we have a taste for sound in great powers and those of us who know electronics make our sound amplifiers, mixers, etc. on demand or on request ... that's why I think transistors are better for amplifiers than the integrated

Thank you very much to all of you for your answers, I appreciate you very much friends and if I have 4 of these transistors and all that is needed to assemble them, you are grateful for their help and time.

I am glad that the information has served you, I am sure that when you master the subject you will take advantage of it.
That circuit is very easy to make, good performance and the sound quality is excellent.
