weird, KLAS post didn't show up on my phone and internets been spotty at the house the last couple days.

I will say that it is a good use of a PWM chip. Im not opposed to using an analog chip and amplifying the signal if it works well. A few varible resistances to tune the circuit by knobs and this would be marketable as it is.

Drum roll: No kit, but I have the printed out instructions from way back then on real paper :-D

September 1997 was the Silicon Chip article. K-3307 was the dick smith kit catalogue number. It used IR2155 self-oscillating drivers.

If you ask very nicely and are very very patient I'll eventually photograph/scan and upload. Maybe you can search it out online, though? I'm not going to try.
