Micrometals 2 mix, usually a stack of 2 T200-2's wrapped with Scotch 27
tape, then Teflon insulated #14 stranded or solid.
However starting from scratch will require about twice the inductance of
just adding 160 to the amp.
Use the Micrometals turns calculators to see if it fits. If not there are
wider choices.

Subject: [Amps] 160M PI network Toroidal Coil
I'm going to convert a SB221 to a single band 160M amp. It seems most of
the amps these days use a toroidal coil for the 160M Output PI network.
Does anybody know what cores are typically used for the 160M toroid?
Thanks
