Hi Ken,
I've only worked on a handful of ARC-5 sets, so my experience is
limited.
I  have seen a problem with one output transformer - o/c primary.

I've seen a problem with the cap across the AF output transformer
primare twice.  
If the mica cap is ok it will test "ok" on a capacitance meter.  
If the mica cap is faulty it will show a few hundred ohms on a
multimeter.
The cap is "buried" and hard to find until you know where it lives.

At least that was my experience.
