I'm really a newb as far as a transistor is concerned.
But, now, I have several good reasons to use them.
I do have a wonderful little portable amplifier that uses a "C839" as an audio preamp for signals that are less powerful than line level. This sounds wonderful when connected with my handmade radio. And, that is the very purpose for specifying C839. For the project, as there are 6 radios to be made, I need several additional units of this transistor.
First, I can't seem to find "C839" transistor on the market.
Perhaps its known by another name or there is an identical equivalent?
How to buy some?
Thank you!

remember,
transistors with Cxxx is most often short for 2SCxxx
2SC839
... sometimes we even see SC839
But there should be good replacements.

Might be possible to find such transistor. Maybe obsolete.

It appears to be obsolete; however, its audio talents are desirable to me.
2N3707, 2SC380, 2SC941 have not yet been discontinued.
Which do you think would be the closest match, and do you think I'm making quite the mistake in trying to use one of these for audio frequency, while its also nearby the coil of an FM radio? It seems that, no matter now nice the little dealy does sound, it may be much better to choose a transistor that can't go above 80mhz. What do you think? And, what would that be?
EDIT: Hey Lineup! I'm so glad you're the one to be answering the "good sounding transistor" question. Our audio preferences are so similar, I think.
