I stocked up from
Fair-Rite at Mouser about a year ago. Digikey also had them as
well as several other companies.

This is why some people appear bright until you hear them speak.

I use 77mix for my AM BCB filters. I have to get some
75mix for the usb cables to my Airspy for VLF.

?I used my giant ferrite VLF loopstick in the aftermath
of Helene here in Asheville for some natural radio listening
in the middle of the blackout. It was beautiful listening. I
used the 1246 turns of #20 over over 10lbs+ of ferrite 45
inches long into a 33k to 600 ohm transformer into a MM-1
Sound Devices preamp using Sennheiser HD620S headphones. It
was incredible listening...the best of my life.
? I ran the gain @60db and had to be careful to avoid
feedback!
?A real bright spot in the disaster! I could also listen
and tell how fast they restored the grid. It was epic. I had
no power for a week and no water for 2 weeks. No potable
water for over a month.

?But no AC grid for miles and miles working? Fantastic
for natural radio!!!
