Agree, and beware if you are measuring voltages with a modern digit al mewter or even a VTVM, either of which will present little or no load. Ancient meters presented a significant load and so readings were guestimates at best.

Replace all the little carbon resistors along with the electrolytic and tubular capacitors.

Makes a huge difference in the end for safety, reliability, and longevity.

Up to you!
