Hi to all,

I have a basic question on working voltages of resistors?

When I used to know tube circuit like the back of my hand, gees the knowledge has kind of flowed out of my brain. Just an couple of days ago, more like 45 years +, I never was concerned about resistor working voltages in most circuits. Today it looks like that could be a problem with most circuits running at a lot less voltage.

I have been noticing that most 1/2 W resistors have a working voltage of between 300 to 350 Volts that are on ebay. I have tried to look at Mouser catalog, but that one is very confusing with so many variables to wade through.

I have noticed either film or carbon has the same working voltage so that does not seem to be a problem. My question is what do you do when a set has a higher working voltage? Do you use the ebay ones? Or were do you get the higher rated voltages.

Or do you even worry about running these resistors at maximum working voltage or a little over. (I have a Philco set that runs around 400 volts on the plates by the schematic but the secondary on the transformer is around 700 volts, have not been able to figured out were the rest is going to).

I hope I have not confused any one to much as I kind of ramble on. At least that is what my wife says.



Thanks Ed.

This is my therapy for keeping my brain from turning into mush in my younger years. I hope.
