The Alpha doent have the luxury of all the room in a Henry 8K which used
that configuration.
A B&W 802 works 160-10 including WARC even in a souped up Alpha 77SX with
the external transformer but dont know about the 76/78 on 30M.

Subject: Re: [Amps] Tips For Winding a Plate Choke
A simpler alternative is to switch another choke in series for the lower
frequencies. This is quite simple to do. Think of two chokes in series
with a capacitor connected to the junction of the chokes. A relay grounds
the other side of the cap on the high frequencies thereby effectively
removing the lower choke from the circuit.
