Hi there,
I am actually looking for an schematic for an amplifier in the region of about 10W rms. Class A or class AB doesn't matter at all. Not more because the case is not the hugest on the planet and therefore the heatsink could not be big.
Because i already own a power supply (2 trannis 25v 60va which sit in an external case with lots of capacitance) i am looking for a schematic.
Hope you get what i mean.
Best regards
Xan

A stereo pair of lm3886 would need more power than my psu could optain. Therefore a gainclone is no option.
Ratings are as mentioned in my first Post 25v 60va. I got two of them and a dual supply capacitor board (CRC 4700uF / 0.82 ohm / 30000uF rated at 50v).
In this situation I'd buy a TK2050 board off eBay for about EUR 21 and use that. Single supply 12V to 30V at 95 mA quiescent, 92% efficiency and they sound really nice.
That would only use one transformer, wouldn't need any extra heatsinking and gets you listening to music much faster. A 60VA transformer could run this at 20+20 easily.

Well something single-railed using 35V would seem to be needed, +/-17V rails isn't an option. 8 ohm load yes?
The cap board was designed for use with dual supply. And i really want to use that. Another tranny is also nö option because there is no more space in that case.
