Audio amplifier

[stigma]

Hello!

I obtained some effect transistors and would really like to experiment with audio ampifiers.
The transistors i got is MJ2955(2 pcs) and BD901(4 pcs), is those usable/suited for audio amps ?

I would really appricate if some one bothered to draw me or link me to an "simple" schematic for an amp that can use theese transistors!

Some good links with basic amplifier examples/basics would also be nice

Regards,
Ole Fredrik

You might try looking at https://www.ampslab.com/c70.htm to give you some ideas.

The MJ2955 is a PNP transistor, it's NPN equivalent is the MJ3055.

The BD901 is NPN, but quite a lower spec than the MJ2955.

Thanks

Thanks alot!

That looks like an nice and easy amp to build to get familar with amplifier design
I'll think i go for that one!
