[Amps] A question!

[Osten B Magnusson]

The old Dentron Clipperton L did not have tuned input
circuits as far as now, but there have been a few on eBay
saying that they have. As I know it, only the Dentron 
Clipperton QRO had tuned input circuits.

When looking at the circuit diagram for a Clipperton L 
there is "an impedance matching circuit" called FI 1 - 
but one can not see what's in there, anyone who knows?
