"Vintage" Allen-Bradley 1/4 watt Various Values 5%**Carbon Composition Resistors NOS 15pcs **These are Vintage Allen-Bradley carbon composition resistors. Due to time and moisture absorption, the resistance value will not read as marked when measured. They will typically measure higher in value. See below notes** **Effect of moisture absorption - Moisture attraction is a generic characteristic of carbon and when the Hot-Molded Carbon Composition resistor absorbs moisture, e.g. during shipment and storage, its resistance value will always increase. Under high humidity conditions it is not unusual for parts to increase 6% in resistance value in as little as 72 hours. The characteristic is reversible, and dehumidifying the parts is easily accomplished either by storing them in controlled, low-humidity area or by conditioning them in a convection oven at 100 degrees Celsius. The chart below lists the proper conditioning parameters.** RETURNS ARE NOT ACCEPTED DUE TO TOLERANCE DISCREPANCIES. TOLERANCE DISCREPANCIES ARE EXPECTED DUE TO MOISTURE ABSORPTION. Information above was taken from the Allen-Bradley Data Sheet found on the internet. These parts are nicely kept surplus parts (see pics). Pictures are of the actual product.These parts are sold in pack of 15 pcs and are shipped in a craft envelope.The Allen-Bradley cardboard holder is not included. SHIPPING INFO (Please Read)To keep shipping costs down I offer "Free Standard USPS Shipping (No Tracking)". The parts are mailed in a standard envelope. I will notify you when the product ships and a picture will be provided.If you require tracking, select the 2nd shipping option (tracking charges applies). Why use Allen Bradley carbon composition resistors? Allen Bradley Carbon Composition Resistors are highly recognized for their outstanding MIL-SPEC reliability, pulse withstanding, power dissipation, high frequency stability, low inductance, rugged construction and dependable performance. Made in USA. Allen-Bradley "New Old Stock" carbon composition resistors are limited. Production has now ceased in the USA. Allen Bradley resistors have a huge following of D.I.Y valve hi-fi builders and guitar amp enthusiasts. A huge amount of old manufactured hi-fi were built using these resistors, hence these antique carbon resistors are close to the hearts of many. They were used heavily in vintage Fenders, Marantz, etc. Carbon Composition Resistors particularly those manufactured by Allen Bradley are becoming more scarce and are in high demand due to their unique characteristics. They are known for their very clean and natural sound. Composite resistors differ from film resistors in that they consist of a little tube with a composite carbon resistor material inside. This makes the resistance, so you only have a few mm of material in the signal. A film resistor is made by carving a channel into a carbon (or metal) film on a glass or ceramic tube, resulting sometimes in a few decimeters (feet) of material in the signal! Also a film resistor always has some inductance, composite resistors don't. **The details above were found on the internet as a convenience. I cannot verify the validity other than Allen-Bradley resistors are highly sought after**
