>> I DO hope that the original resistors are good
Never saw thtat in a 20 (have restored 3 of them). All were off.
Thing is, 20 used the older style, large metal caps (made of solder) and ceramic body resistors. When I opened one of them, it was a thin carbon (or carbon covered?) rod imbedded into those solder caps. This cannot possibly be very stable, even though over the course of my dealing with those I saw some being righ in the value, especially smaller ones.
I distinctly remember one #15 resistor (250K) being 800K, and another fully open.
Maybe you get lucky, but her's the thing: it is few of then, easy to replace, and they will sooner or later (thermal cycling) go totally bad. I'd replace them.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
