Hi Tubeman,

Welcome to the Philco Phorum.  Phamily Phriendly Pfun with Phine Pholks Phull of Philco Phacts. (See a pattern here?)

Both of your radios look neat.  I used to have 2 Eicos, one bought from an electronics shop, the other a gift from my father.  I loaned to a step in-law for his father who was an engineer for Emerson in the 1930s.  Unfortunately, upon the death of this gentleman the step in-law never retrieved them.  However, I rarely used them for any AM or AM / SW radio that I repaired or restored.  Don't let the lack of a signal generator stop you from starting your restorations.  Whichever one you start with, definitely get around to restoring the 42-350.  Push-pull outputs and 12" speakers make for BIG sound.

Philco has a rather unique method for getting the inverted signal for the grid on the 2nd tube in the Push Pull output stage.  they get it from the screen grid of the first output tube.  Note the lack of a phase invertor tube.

+1 on the comments from others.  Recapping is mandatory, most especially for the filters, but replace all paper / foil caps also, especially audio interstage coupling caps and B+ bypass caps.

There are 2 methods of dealing with the rubber rot:

• Replace the individual wiring either by totally gutting the chassis or one wire at a time.  Remember that lead position (dress) is important, especially in the RF and IF circuit but in the Audio circuits also.
  
• Cut one end of a wire, clean off the rotted rubber and sleeve it with "spaghetti" or heat shrink tubing, then reconnect it at the end cut off.
  

Keep us posted, please do not hesitate to ask questions, and keep coming back!
