Resistor reliability question

[Chad Hauris]

I haven't had many problems with bad resistors in this age of set, but I would check all of the voltages at each element of each tube...problems I have seen with resistors often relate to those which have been damaged by overloads due to bad bypass capacitors like at a screen grid. The voltage check will lead you to the bad resistors if there are any because you will have an off value or no voltage.

The RF generator has been such a help to me with problems such as this.
One helpful thing is that you can make the signal very strong and this can help get a signal through a misaligned set so you can align it. have seen several cases where an alignment needed to be done to pick up any stations and I think it was just due to component aging.

'Tis true, but one of the worst alignment jobs I had was because a set had been hit by lightning and rendered inoperable about 30 years before I got to it. Apparently over the ensuing years after the lightning hit a few people in the family that owned the old Stromberg-Carlson radio thought they could get it going again. One of them found a whole mess of loose screws--and tightened them!
