[time-nuts] Need help with transformer core

[George Dubovsky]

Hi Corby,

I have the old data on that Indiana General part: it seems to be O-6
material - 4700 initial perm, 6000 max perm, up to 0.5 MHz, 210 degree C
curie point - and F1152-1 is a 36x22 mm ungapped ferramic pot core - AsubL
min =11530. If you need more data, I can probably scan the relevant pages.

Regards,

geo
