Default Class D amplifiers on National Chips

Iīm wondering if anyone is interested on a PC board for a
class D amplifier based on the National LM 4651 and 4652, the first being the driver for the Mosfet chip 4652.

National doesnīt have the board available and I donīt
think it will have it in the near future.

All the files for the boards are available in the Nationalīs
website, including the Gerber files.

Perhaps somebody like Brian GT as he did for the LM 4780 could
be the one to embark in this project, who knows?

Anyone interested?

You should try making your own pcbs, lets you design to your own needs.

Or just get the ones on nationals site and print them off yourself and etch.

Its fun.
