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
