Then you missed a great period in America's history. G

The "boosters" were just little autotransformers with a tube base plug
and a tube socket wired to them. When placed between a CRT's base and
it's socket connector they boosted the filament voltage by about 20% so
the "picture got bright" again for a few more months before the filament
finally burned out.
