Eh, nevermind... And I guess I'll order 10 cores then since they're basically half the thickness of the originals.

I'll go for 20 again. I can probably stack 8 at a time. Now to find people for the remaining 20.


30/50 cores accounted for! The core is here: Link2

Put me down for 10 please.
Time I dusted off the IH parts box.
Thanks
-Rich

p.s. That doesn't mean you have to close the group buy.
I bet the 50 unit price applies to all quantities between 50 and 99.
Would the plan be to share the cost of shipping from Dexter to Ben,
then each pay for shipping from Ben to each?
Small flat rate box or first-class mail large envelope (stiffened w/ cardboard) would do, IMHO.

50/50 cores accounted for. Time to get in ends Saturday.


Hi Rich,

If you look farther up the thread(maybe in the first post), I mentioned that 50 was the minimum, and I'd keep the buy open until Saturday. In any case, 100 would be awesome, because we'd get price breaks and pay less.

Thanks everyone who's joined in so far!

-Ben

Hi ben123324

If I was going to make a 2* 1kw transformer(200volt 10khz) how many of the cores would I need. I might be interested.
