[GreenKeys] What ever happened to "Pot Cores"?

[Don Cunningam]

Yes, those were mentioned in depth in the DT-600 literature.  That is 
available here, by the way: 
http://rtty.com/development/tu/dt-600/dt-600.htm .  He has the 
schematics and the building information on this site too.  Nice read.  I 
have searched the internet, but the larger ones seem to be a lost art, 
far as I can see so far.
