[Heathkit] [Heath] SB-102 part needed

[Jim Shorney]

Nice work. As a teenage ham, I didn't have the tools necessary to make a
"proper" repair to the lever knob. I found the faux chrome car stereo knob in a
spares bin somewhere, and decided to give it a go. The chrome finish actually
looked pretty good together with the brushed aluminum skirt of the Heath knob.
I never had a failure with the Load control lever knob, there's a lot less
stress there.
