I have one.  Built by a ham who lived on my street but who moved away  
before I got really interested in hamming.  How I got the amp he  
build, I don't know, but perhaps from some of his family who still  
lived there.

The amp has a Masonite front panel, two 866's for rectifiers and a  
hand wound (or re-wound) plate transformer.  The ARC-5 tuning inductor  
and plate capacitor are there, too.  Two wire lamp cord for a power  
core.  No shielding whatsoever.
