RE: dead horse grid stoppers

kkcinc, hi. The problems with carbon comp: 5% is normal. If you want better be prepared to match from quantity. Then, with use and depending on how much E they see, they will be inclined to drift. Another problem has to do with how they conduct in the first place. Analysis will show micro-arcing from granule to granule. Multiply this by thousands of times. In circuit they can be enticing to some with effects described as warming things up. I think you are much better off with precision carbon film if it is carbon you are wanting. I have used non-inductive ww & bulk foil types (Vishay S102) as stoppers with no untoward effects. Scope to make sure there are no high frequency oscillations. I tend to like wire wound and carbon film and not like metal film, metal oxides, and carbon comp. There are others who would reverse this lineup. Try and listen. Ultimately the final test is the hearing. Happy Listening.
