Broken Brass Tuning Band on TRF
12/16/2005 2:29:39 PMDoug Criner
These narrow, continuous, brass bands are used to gang together the three tuning capacitors on many TRFs. They show up frequently on AK a.c. sets, but this one is on a Crosley "Bandbox" 601.

One of the two bands on this set is broken in two. It looks like somebody spliced it in the past using a 1.5" piece of spring steel and tiny, peened-over rivets. It's broken at one of the splices.

What the best way to either fix or replace this thing? Thanks.

Go to your local hobby shop and they should have brass strips, pick the one closest to the width that you have and use it as a splice. Cut it so it extends about 1/2" either side of the break and solder it together. Make sure you clean your band with fine steel wool so the solder will stick. Use "NO" more solder than it takes to hold it, you dont want to make it too stiff. AES used to sell material to replace a lost or broken band but I dont know if they still carry it or not.
