Lightbulb 200W Digital AMP

Hi everyone,

I would like to hear your opinions about this design. it was published in Electronics Now April 1997 (RIP). What I like of this design is that it doesnt use a transformer for the power supply.

If somebody wants the whole article please let me know...it is a 9.4M file!!!

yeah, no transformer in the power supply is pretty cool, one is shown in this thread as well: DC-DC converter

There are several chips out there that are similar to the tl497a.
