[Shaleradio]

ÛPicked this working radio up at an estate sale.  It's a cathedral.  Since it was working, I'd thought I'd just recap and replace out of tolerance resistors.  I've run into a problem I need advice on.  The wax cap in the picture goes from Bakelite block #26 and ties into #2 pin in output tube #42.  Where it sits is right behind mica cap #30.  However, on the schematic and the base view drawing it clearly is not original and was added.  I "thought" the caps in that Bakelite were mica.  I ordered two 100pF@500V mica from Just Radios just in case they were needed to replace but ...now I'm wondering if it was added because the Bakelite block was failing and if so, did I get the correct replacements?  I've never seen a wax cap installed to support a failing mica anyway. Any thoughts on this are greatly appreciated. The cap is marked 30-4024-m.
Thanks,
Mark
