LM566 VCO seems unobtainable.

Yes, triangle oscilator can be done with MC1455 or with some OP.

The funny magazine is sold in Poland as well I think.
BTW the amplifier is pure junk.

The schematic looks just slightly under average, but PCB layout is terrible.

There are better ways to do it with these parts (and TL07x op-amp triangle generator and LM319 comparator, standard stuff).

One of the things I have in mind is making a simple DIY-friendly class D module with through hole parts (except a few SMD caps) and a "DIY friendly" double sided PCB (no tracks on top layer, just continuous ground plane), and find out how good can I get it.

I'll be waiting with interest on this. My PCB done in this manner is already doing fine and has a very large number of SMD parts - zero. :D But innovative stuff such as better gate drivers will be appreciated.

This JBL class D amp for subwoofer can be made without SMD parts.

¡Al final!
Finally! The wait is over. Will there be a fitting SMPS as well?
