ceramic disc like resistor
 

hi all this motorola set i have has what looks exactly like a ceramic disc cap but it is a 220ohm 2 watt resistor and without it the set dont work at all i thought it may have been a thermistor but its not but only a resistor.this set had the leads twisted together for it to work but i cannot get this type of resistor so would a metal oxide type resistor be a good sub for this.the set works with the leads twisted together but dont know what it may effect in the set for the long run,a resistor like this is there for a reason and would like to put the equivalent back if possible. the old one is about 1 inch in diameter but it is burned. called moyers and i dont have a part number except the number on the old one but no listing of it. any ideas or heard of this resistor or what i could put in place but im not sure if i could use just a 220ohm 2 watt metal oxide 5% resistor in place because the size of the old one maybe like a 40%, i dont know.:scratch2:

I don't think you'd have any trouble using any 220 2w resistor you had. 40& tolerance is about 130-300 ohms! Using a 5 or 10% ain't gonna hurt nothin'.

well the sams calls for 220 ohm 2 watt but the size of the old one concerns me as i was thinking there was a % difference because the old one was so big around but yet flat just like a ceramic disc cap, looks identicle.

well the resistor just burns up so i think its another mistake on the part of the sams folder as not listing this resistor as a thermistor because it looks to me its right inline with the ac in so this would make it an inrush current limiter so the resistor wont work but rather burn up befor it can supply the circuit. has anyone heard of a big thermistor like this being 220 ohms cold 2 watt, because the resistor theory is out, it dont work,lol...

Bypass it. It is a thermistor that does exactly what you say.

well the set was made for either 110 or 117 vac so now we have 120 vac and sometimes the grid is higher so would it be wise to try to get one just to protect it alittle being its an old set.

Put a CL90 thermistor in there. Its only for soft start.
