[Boatanchors] Antenna trimmer mod for Hallicrafters S 76

[John King]

I have a nice Hallicrafters S76 that I am going to refurbish. It has a hole in the panel for the antenna trimmer installation, but no antenna trimmer. I want to install the antenna trimmer.

Anyone have the information or instructions for antenna trimmer installation in the S76? Any references to magazine articles, drawings or mounting instructions?

I am not sure whether the trimmer was a modification or at some point a factory installation.

If you have a A76 with the antenna trimmer installed, a close up photograph of the mounting would be very helpful. Any assistance you can provide will be greatly appreciated. Thanks and 73, John, K5PGW
