Its not insulated at all but if the two ends never meet should it matter at all? what i was concerned about is its conductivity i tried with a multimeter got around 0.1 ohms which i think is good enough but wasn't Complete sure.
If you are extending the legs of the capacitors then there must be a join somewhere .
Put the two leads of your multimeter together and you should find what you are measuring is the resistance of the leads of the multimeter not the short length of wire.

What do you mean by join somewhere? Do you mean when the two Leeds join to the capacitor or when the two Leeds join to the PCB. Also my multimeter is a little smarter then that if the two probes are directly touching each other it says 0 ohms. Also my multimeter is a uni-t UT139A i know its not as good as a fluke but its probably good enough.
If you are measuring = 100milliohms on a 2 inch piece of wire-
BIN the wire !
I have a HP 6.5 digit industrial assembly line systems voltmeter and I have just measured a 2 inch piece of thin copper wire using a 4-wire circuit and its less than - 0.001milliohms .
Are you saying you are going to cut off the legs of the capacitors and solder your longer ones DIRECTLY onto the capacitor base connections ?
IE- not extending the existing leads ?

No i am going to extend the leads my idea is to solder the Steel wire directly to the legs. the legs are atleast 2 cm away from each other so its probably fine. Also is the uni t multimeter safe enough to measure the voltage inside the radio.
Oh and also copper is More conductive then steel

The meter is okay for the price but if I was you I would get better quality leads for it , I have seen those type of leads get cut into on metal chassis which most old radios are based on.
Just watch the high voltages.

Well i am actually using alligator clips for that also the Main reason i asked is that can it actually go to 600v dc.
Your radio wouldn't be above 350V DC working so it would be okay.
The tubes Plate/ Anode/HT+ voltage in the E range of tubes is 250 V DC .
The tubes Plate/ Anode/HT+ voltage in the E range of tubes is 250 V DC .
I know that but some of my radio's probably have higher voltage i own 10 different tube radio's
In that case you want a 1000V multimeter as many very old radios have 500V DC working power supplies but get a very good pair of silicon leads for your meter they will last years .
Post 171 you said you had -quote-"10 different radios" if you are a serious collector of old radios then some are going to be 500+ V working voltage.
No you don't need a 1000V meter but you are getting near the limit of your meter and testing AC transformer output requires a higher than indicated voltage due to AC peak voltages.
It can blow some digital meters which are only good for lower AC voltage readings .

> do i need a 1000 volt meter Just to repair a 500v radio
There is a Safety Class of meters which only goes to 600 Volts. That's what you want.

Ok but one other question why does some of my solder joints turn a little White after a few second.and is it okay that it turns White or is it a bad connection.and yes i have tried reheating.
