Topband: Norton preamp

[kurt-erich.finger at arcor.de]

While Dallas Lankford uses FT50-75 toroids in his design of a Norton amplifier, I found an article on www.qrp.pops.net/preamp.htm where a Norton amplifierwith binocular cores BN43-2402 is described (a design by Joe Reisert) . I just tried to make the windings, however, I discovered that it is impossible to do a 12db amplifier with AWG 32 wire even if trying do the 9.5db version which uses 9 windings you have to squeeze the wire into  this little binocular. (I could use a smaller wire, but I don't have a smaller wire at hand right now)
Can I replace the BN43-2402 with its larger brother BN43-202? Second question: Wouldn't a BN73-2(4)02 a better choice?
