Hi Steve,

OK, if that's what Andrew said he used, I'll happily accept that.

The cores in mine were different to 73 mix, but he may have changed makes or suppliers over time, or perhaps more likely, Fair-Rite may have changed the formulation, as they have done with other mixes.

In the UK, it used to be quite difficult to get hold of different Ferrite materials, unless you bought directly and in quantity. Fair-Rite only became easily available a few decades ago, when the main distributors started stocking their product range.
