i dont even think its a resistor, but theres nothing written on it, or the other one

So basically we were right, even though you kept calling it a resistor, which it's not.

here is a suggestion for you ,if your going to work on anything that your not familiar with, before you go running around asking for a part that you think you may need for it , i suggest you learn to diagnose things. step one i.d. the chassie with the type and number get a schematic for it, step two locate what componet looks bad [ if burnt ] from schematic ,find it on the parts list or from schematic itself they mark it with its value on it, or a part # then when ask for a resister or varistor or what the case may be, then someone can help you and know what your trying to say. i know the way i type may come across maybe harsh thats not my intentions ,i think maybe if you learn some basic check out skills it will help you in comuicating what you need, i dont think anyone has shown you the basic's in checking out problems . it would sound different if you were in person teaching you then it comes across typing what a person means to say,so dont take it as being harsh on you, have fun working on things just learn check out and learn what each part does and how to i.d. them.

The Specs are 120 ohms cold 3-5 hot.

It is a resistor

A CL-90 is a perfect replacement

Its an RCA KCS127 Chassis

It took me all of about a minute to grab the sams and verify what Eric said in the second post....

Eric said thermistor.

You just said it's a resistor. And your description just described a thermistor. Even you are confused.

Besides, we all said it was a thermistor. He was the only person claiming resistor.

God knows that I've been hard on the kid but lets all back off a little. Hairs are getting split a little too thin here.

AFAIK a thermistor is a resistor, one that changes value with voltage/heat, but a resistor nonetheless.

We all know what each other is talking about I think.

Yes but you wouldn't put just a resistor in place of a thermistor. Just saying. They have their differences.

Thermal+Resistor=Thermistor

VDR/Varistor=Voltage Dependant Resistor

They are all in the resistor family, symbolized as resistors and valued in ohms. We know the specific type of resistor by the package description

There is zero confu

Im done with this

In this case, for this specific thermistor you would just bypass it like every tech in the day did that didnt have one on the truck.
I have used a decade box to find a suitable fixed value for both thermistors and VDRs that were not available.

The only application you cant effectively sub a fixed resistor is for a VDR that is used as a signal shaping rectifier.

Like CTC17 said, you can just bypass it for the time being.

I would replace it as soon as possible though, it's there to soft start the set when it's turned on cold.

www.mouser.com has the CL-90 their part number is 527-CL90
Here's a direct link: http://www.mouser.com/Search/Refine....yword=527-cl90
