Thanks TA Forbes for the correction. Iwas starting with the tone control ,the shaft is broken off even with the the nut. I unbolted it from chassis and discovered something is missing ,on the contact area you can see where it's shiny but nothing there. The part # is30-4168 after a lot of searching I found one that is Philco 45c part#30-4178 . Would you know if that will interchange? Thanks
I found it on a link from the philco site and will have to order it and there is no picture.
