Default bd238/bd237 amplifier?

I have three bd237 and three bd238

can i make a power amplifier out of them?

i don't care for power, it might as very well be 1W, but if it has good characteristics i might try any schematic you might suggest!

Hello,

amb.org has a preamp/headphone amp on such a low power transistors, Alpha 20. You can use it as small power amp.

The α20 Line Stage Amplifier

Or simply, use a these power transistors as the current booster for an OpAmp.


Thanks,
Routhu
