Re: Source for Type 31 Toroids

I have just opened a Mouser account in France and ordered a quantity
of, 2631803802 = FT240-3 Fair-Rite.

I hope they're OK. Thanks for the tip on the weight data Ian, I'll
check them when they arrive.

You should have no problem, as Mouser are one of those "dependable
suppliers".

Their catalogue prices are not the cheapest, but Mouser's free
international shipping makes them the least expensive way to buy
Fair-Rite products in the UK. Do they have the same free shipping offer
to France?

Re: Source for Type 31 Toroids

Hi Ian,

Yes I have long wanted to have the availability of Mouser components.
There is FREE shipping over a minimum amount (around 80 Euros, I
think), I made this up easily by ordering 15 toroids and some push
button caps for my KPA 500.
