So far, so good!

Nicely made RF choke which are becoming hard to find these days. I have used a lot of these chokes over the years and will continue to do so in the future. Latest order was for a new project and stock build.

Chokes are chokes, what can I say; they are good to use in RF design using vacuum tubes and will be used for that purpose. I enjoy that they are available through you at a good price.

Works well, looks well made as one would expect from Hammond!

Great item! I use these to bleed static off to ground from my ham radio antennas. They are transparent to RF at the frequencies I operate on, and help prevent radio damage. Price is great and shipping is reasonable.

RF Choke - 2.5 Mh - Quick delivery, good packaging, and a reasonable price ... I would buy again from Antique Electronic Supply

Used this choke for active antenna project-much cheaper building one yourself than buying a commercially built one-good price for a somewhat hard to find device.
