We have been answering queries about the large 4" OD Fair-Rite 2631814002 toroids <https://proaudioeng.com/fair-rite-4″-toroid-core/> which have been out of stock for a while but we now have good stock.
It should be noted that my extensive work showed the effectiveness of these oversized cores to be limited to 20M and below, and the standard-size (and much less expensive) 2.4-in o.d. cores to be the superior choice above 80M. W6GJB and I have used them only on 160M.
