New subject: power transformers (was imsai 2)

18 Aug 1999

<Well, as I've said before, there are transformer kits available in the 
<UK. THey cost a little more than a normal transformer of that power 
<rating, and consist of a former with the primary windings pre-wound, and 
<a pile of laminations. You get to supply the secondary wire, and wind it on

As someone that has wound audio and power transformers from scratch it's
a pretty trivial task and can be very useful.  Used to be a time the 
ARRL (USA) Handbook for Radio Amateurs had all the tables.  Though given 
a random core it's pretty easy work all the numbers out after finding out 
if it's big enough.
