Okay -- so tell me what a latching relay is, and I'll be all set.

Pardon me if I missed messages in this thread where this was already 
discussed, but didn't John Farrington and Monica build their own PWM 
controller? Oh yes, I have it bookmarked here: 
http://www.prismnet.com/~jrf/SubPics/page017.html.

(By the way, and completely OT, can somebody suggest a likely place to 
look for basic electronic components -- preferably someplace that would 
have parts lists or circuit diagrams for lots of consumer electronic 
gizmos? I need to replace a component in a JVC stereo, and it's too 
damaged to read what it was so I need to go by the number printed on 
the PCB.)
