Simple 15-25W amp on 12VDC?

Both TDA1562Q and TDA8566Q come in DIL-bent-SIL package, which is the NXP (Philips) equivalent of multiwatt (ST). The type of heatsink is the same. Take a look at the package options on NXP datasheets (the letter after the main number "Q" tells package type).

You can have it if you want it. Giving it away will save me from starting another project I don't need.

Thanks, but I already have a TDA7376B on its way. I appreciate the offer though.

See 41Hz Audio:AMP6-BASIC kit

Here is a quote from the web page:

"The output power is around 2x25W RMS maximum, into 4 ohms at 10% THD+N. Up to about 2X15W, the THD+N is below 0.1%. "

Hey, that's actually the one I was thinking of getting if I don't put my own together.

Could you point me to a heatsink that would match the hole spacing for mounting one of the NXP chips?

Never did get any TDA7376B in so I decided to go with TDA7393.
I started a new thread with some questions. Anyone help?:
