Not really, a Philco 20 used what was known as TRF circuit, basically the only thing you can do is adjust trimmer/padder condensers for gain, I don't think it even needs a neutralization adjustment since it uses screen grid tubes for RF amplifiers #24s or #35s. I'm not sure how you can get the dial to track on one of these, the factory instructions would probably say.
