40-180 Recap - Looking for tips/advice
#21

I decided to peek in the drum, and see how hard it would be to replace the wires. It turns out it's very easy. All you have to do is take out the staples around the top and the bottom. Leave the ones along the seam in place. Then unsolder the wire on the metal tab, and carefully slide the drum off.

It's basically a big X inside with wire wrapped around it and tapped in a few places. There is also a capacitor and resistor in parallel in there on the white wire that runs to the antenna terminal on the radio. I didn't notice them on the schematic at first.

I desoldered the terminals, cut new wire to the same length, and soldered them back on the new wire. Replaced the cap and resistor as long as I was in there. Slid the cardboard back on, re-stapled it around the top and bottom, and it's good to go again.

I attached a picture in case anyone wanted to know what it looks like.
