Hi all, first time restoring a Philco 38-5. The set was partly recapped before and i did replaced wax caps under the chassis. I can hear the oscillator on nearby radio on my workbench but cannot pick up any stations on the Philco.   I have not checked inside the black ceramics under the chassis. How do you open them ? any pointers will be greatly appreciated.  

Regards
Dirk
