Here's the datasheet for the TDA7492P. At 18V, 20W output power at 1% should be reasonable.
Datasheet TDA7492P

Some other interesting stuff, like this 2x15W amp - PAM8610.

I have started to install my other amp modules (TPA3110 and TDA7429) in the three plastic cases I ordered from German company http://www.reichelt.de.
Wanted some higher power for a pair of speakers that don't really sing out nice and fine at 3W. That isn't really true, but still I want some amps with higher power ratings.
I am also waiting for a pair of TPA3118 (60W mono each).
So, just som few shots of what I am up to right now:

That was what caught my eye. We have some few shops for electronics in Sweden and a bigger one that ( :confused: ) sends stuff from the Netherlands. Also we may buy stuff from Farnell and Mouser (P&P added :eek: ) and then there's this German company - Reichelt - that has also a lot. I found the 2SK1058 in that shop and at a VERY good price.

Anyway, I am more of a metal box fan, but the colorful plastic boxes looked so smart, but to be honest. It took me 10 minutes to open them up. We Swedes tend to read the manuals when nothing else helps, and the manual (a piece of paper) said I had to press the sides of the box to open it. No screws (to be lost), just snap-together. The boards are screwed on a piece of sheet metal (aluminium/zink, got tons of it at work)
