Just thought I'd let you know... Any other news/comments? jarthel quote: Originally posted by falcott Hi, I've just heard from Parts Connexion that Riken is no longer in production. Just thought I'd let you know... Any other news/comments? old news already :) mirlo Who else still makes them? I never liked the Riken carbon comp resistors because of the gold plating on the leads. I don't think it does any good for the solder joints -- gold is good for connectors, but not soldering ... Anyway, I think Ohmite probably still makes carbon comp resistors, maybe Xicon. Anyone else? -- mirlo CarlosT I just ordered some little carbon comp Ohmites...they go by the trade name Little Demons :devilr: http://www.ohmite.com/catalog/pdf/little_demon.pdf Any good? dsavitsk quote: Originally posted by mirlo Anyway, I think Ohmite probably still makes carbon comp resistors, maybe Xicon. Anyone else? Kiwame, available from percy, parts connexion, and a few other places. turnA_zpoint I know some .. If RIKEN is resistor saying "Rikenorm" in japan , so they are to be selling now only stock. http://www.wakamatsu-net.com/biz/ this is very famous shop at AKIHABARA in JAPAN say "WAKAMATU" but I dont know to be able to buy from other country. I attach the list with some translate Jananese to English. CarlosT Is there anything inherently wrong with carbon composition resistors for use in chipamps? I've heard pros and cons: Cons 1- have more drift and noise 2- may break down with sustained high temp use Pros 1- have a warmer tone...maybe due to our perception of drift 2- old school? falcott quote: Originally posted by CarlosT Is there anything inherently wrong with carbon composition resistors for use in chipamps? Peter Daniel perfers them in his chip amps: http://www.diyaudio.com/forums/show...2232#post892232 also mentioned in other threads. Old skool I like! :D wim www.ae-europe.nl is advertising with Rike Ohm resistors on their site, so..... Apex Jr I should mention I stock: NOS RC (Commercial) RCR (Mil -Spec) Allen- Bradley IRC International Resistance Corp Airrco- Speer Stackpole TRW Ohmite And others in Carbon Comp resistors 1/8W - 1/4W - 1/2W - 1W - 2W Most people prefer the Allen-Bradley but since these are so hard to find depending on the value they will settle for other Manufacturer's Steve @ Apex Jr. drwkng for what it is worth, riken is not carbon comp but carbon film. falcott I did a google. According to these people, Riken is carbon comp... http://www.thlaudio.com/jpnohme.htm And according to these people, they are carbon film... http://www.angela.com/catalog/resistors/Resistors.html But according to these people, they are carbon comp film ! http://www.audiokitmania.com/resistor.htm What is the difference :confused: jarthel quote: Originally posted by falcott I did a google.
