folks. I am in the process of replacing this part however I cannot find the right size. the toroid measures

1-3/8 id 1-7/8 od ht 3/8

on Brooke Clarke’s website he mentioned FT140-43 as a replacement. I got one from epay however it is

1-3/8 od id 7/8 id ht 1/2

so not sure if this will fit

anyone know what the original part number is? thanks Jeff. N2IA
