Yes, I think you're right.  At the C/S experimental station Tesla would
occasionally excite an experimental coil using direct coupling to the large
oscillator's primary tank circuit or some variation thereof.  See
www.tfcbooks-dot-com/writings/images/discover.jpg for an example.  Does anyone
on the list have practical experience with this form of magnifier?
