Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shaped, 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.

Note: All values are 10% tolerance.

The manufacturer is proprietary information but the country of manufacture is Japan.

they are most likely still made by XICON as their catalog stated 8 years ago.

The leads are ~1" in length.

No. If you ever receive resistors from a supplier that are outside of the posted tolerance, you should reach out to them to get a refund and/or replacement. I would guess you purchased 20% tolerance resistors from the other supplier, meaning a 220K resistor will read 176K-264K. The spec sheet for these resistors says 10% tolerance. So, a 220K resistor would read 198K-242K. That is as tight of a tolerance as you will get for carbon comp resistors.

My favorite resistors to work with, and my favorite company to get them.

I've been with Antique Electronic Supply since long before there was Tubes And More. They always have the best parts and service as well as fast and accurate shipping.

1.5k ohm resistors are hard to find but not at antique electronics supply. THANX

Only resistors I like to use when restoring an old amp are carbon composition. These are cost effective, look right and when your amp is cooking, they sound right in the signal path. Highly recommended, don't cheap out.

A story: I had a customer years ago who had me replace all of the resistors in his signal path with these resistors, and all the caps with Mallory 150 series in his Hot Rod De-whatever. I like those amps for what they are, best amp you'll find for the money, but I'm no fan of the harsh tone. It was an expensive job and I tried to talk him out of it. But in the end the goal was achieved and I even found myself liking his amp. I wound up doing a bunch of reissue Fender amps this way and in the end it was worth it. Great product.

Mostly only used for cosmetics now. Unless you are actually working with RF, these things are just not worth the price, and the future headaches. These are not as noisy or drifty as those old silver stripe 10% resistors in your old Tweed Fender Whatzitmaster Pro, Brown, Champ, Harvard, Concert, Deluxe, Vibrolux, Tremolux, Vibro Champ Twin Princeton amps, but just wait until they are old enough to collect social security and they'll suck just as bad. This composite is hygroscopic so values can and will change with humidity and drift with heat. The MOJO FACTOR. If you want that audible mojo, the Chinese make some really cruddy carbon comps, and I know where to get them. You also get even more Nyquist noise, more shot noise, and more thermal drift as well as drift with humidity. These old resistors actually do have their places, and sadly where they would be the most useful in an audio application they are also the most vulnerable to having problems too, and that's up in the Meg Ohms ranges, where carbon film and metal film resistors are really inductive. The ONE redeeming factor with carbon comp resistors is they are NON-INDUCTIVE! These would show up in old analog TV tuning circuits otherwise a carbon comp would either oscillate, pick up stray RF noise, or do both. I prefer the Brown Devils and the ceramic carbon comps, but they are now so expensive and so seldom used, almost no one carries them anymore. Modern stuff uses a planar thick film, instead of a spiral cut film, so those are all modern non inductive resistors, which can dissipate upwards of 500 Watts.  Yes those are expensive, and it makes these look, a little less expensive. Honestly.... Just uses carbon film, and metal film in key places. If you have 1 Ohm resistors for bias setting buy the 1%, 0.5% or 0.1% precision resistors, or you will destroy an amp, so DO NOT EVER USE THESE FOR A BIAS PROBE RESISTOR! !!NEVER EVER!! If you want to use them everywhere else, cool, but not for a bias set probe.

These look great in amps. If you are looking for accuracy values order a couple of sets to get the best accuracy. They are not too far off the value thought I just needed some that were really close in value.
