Yeah, dang resistors
I replaced 75% or more in the last few sets I restored.
When I first started on this set, I ordered some 1/2 watt carbon composition resistors from Mouser with the intent of keeping it authentic as possible.
Unfortunately, I was finding many of the new ones to be out of tolerance already! Always on the high side - just like the originals. I've also had a hard time finding 1 and 2 watt carbon comps. So, I switched to metal film and metal oxide. Not authentic, but very stable and reliable.
