There is a tip that I've heard of but haven't tried. The theory is that the nichrome wire oxidizes at point of contact on the solder lug. Chip away a small amount of the enamel to gain access the oxidized area. Clean up the connection. Not sure how you reconnect nichome wire short of crimping or spot welding. Use a bit of JB weld to replace the missing enamel and color to match.
About the same time the 87 came out the National Company out of Mass produce a receiver called a SW-3 which a similar problem. Have serviced several of them have used Ohmite Divide ohm resistors. They have a side that the nichrome is exposed and slider that can be adjusted from from one end to the other. If more taps are needed add more sliders.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
