Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shape, and then baked. Resistance decreases as temperature increases. Resistance is more prone to drifting than with other types. Standard 'classic' resistor.

Sold in multiples of 5. Pricing is per pack of five (ie, entering 2 equals a total of 10 resistors)

  • ½" watt
  • -55° C to 125° C operating range
  • 350 V working, 700 V overload
  • Low inductance
  • Low capacitance
  • Better pulse endurance characteristics than film type resistors
  • EIA color coded

These are modern carbon comp resistors. They will NOT have the same classic sound as the old cheap carbon comps made 40,50, 60 years ago. This brand also tends to skate beyond the tolerances of +/-5% or +/- 10% for 1 watt resistors, so buy extras. They are okay for cosmetic appeal in a restoration or repair of a vintage amp, but you will not get that magic classic harmonic content of a 50 year old carbon comp. These are made mainly for pulse circuits now. They still have issues with shot noise, white noise, & Nyquist noise, but that magic mojo is just not there. The Chinese are making a very crude formulated cheap carbon comp now that exhibits the tendencies and sound of the older carbon comps. Those are +/- 10% for the half watt, which is a pretty honest assessment compared to these Xicons, which can be as musch as 10% out of spec for a 5% resistor. I will buy two extras for every single one I need and 50%-20% extra so I can hand test & select resistors that are closest to spec. Ohmite is a better option and forgetting about using these at all is the option yet. The other manufacturers that put their name on these are Kamaya, Ohmite, and sometimes IRC. I will not divulge the best carbon comp vintage resistors, but I will say they are NOT Allen Bradleys. Don't EVEN waste your money on NOS Allen Bradley resistors. Buy these instead! The ABs are ALWAYS out of spec, and they were a higher grade resistor, so no magic mojo, just worn out, aged, over priced junk. Avoid these like plague in tremolo circuits. Usually a bad cap and drifty high value carbon comps is why those stop working. - March 15th, 2015

Never rework Fender Amps without these. Metal film or carbon film can not compete. It seems that the manufacturer shifted to Kamaya from Xicon recently. This movement is all welcome, because Kamaya is much stabler in the resistance value than Xicon. Thank you Antique Electronic Supply.
