PAM says... I wish I could find carbon comps (decent values) for two cents each! Those days are long gone around these parts. Pete www.mouser.com looks like a lot of Carbon Film ones are in the 3 cents each price range to me..... those are 100 lot prices.... so its 3 buks a 100 They are a Dime Each if you wanna onze twoze them ..... so then its 3 buks for 30 of them......

I have the following pkgs of resistors, sealed, all allen bradley: 50 per
pack, 5%, $5 per bag 330 ohms, jan rcro7g331js 5 bags $5 per bag 1000 ohms RC07GF102J 3 bags 2200 ohms, JAN RCR07G222JS 3 bags bag with about 25 new resisors of various types, some precision (1%), some carbon up to 1 watt $3 bag of metal film resistors, mostly 1%, some may be better than that, $3 shipping will be no more than $4 now matter what you get, could be less Bill "David Austerman" wrote in message news:d017f0b4a4c7a5593add915b9f5a986f.32924@mygate .mailgate.org... Hi, looking for some misc carbon comp resistors in 1/2watt size. Like to find misc values (e.g. 1meg, 220k, whatever) to keep for my amp/boatanchor projects. if you have any extras laying around whether 20 or 100 or whatever qty let me know at . thanks, dave, n5wnm, okla city, ok -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Pete No Pete... they are the newer packaging style... re carbon resistors see comments from the other Bill Turner W6WRT regarding them.... I agree with him.... long term they aren't as stable as the newer metal film resistors John k9uwa How stable do they need to be in an old radio where components values can vary, sometimes by quite a bit, and the radio will still perform just fine? |

Without that information, the question can not be answered. -- Bill W6WRT The question is pretty much answered by the fact that most antique radios used 20% carbon resistors. Many of these original resistors have aged upwards of 100% over time, and the radios often still run "just fine". The manufacturers saw no need to use high tolorence components, and most of the circuits are self biasing and self compensating to some degree. Vintage radios aren't rocket science. Good NOS carbon comps from reputable manufacturers are fine. Pete k1zjh |
