A safe bet for the working voltage would be 300. timmy 05-22-2017, 07:00 PM I was able to figure out that this cap has a silver dot far left and identifies a molded paper cap and also it's rated +20 % and the other dot 1 and 2 tells the pf which I can't figure out, both brown colors indicates 1 for each and the multiplier is 1 million. This is where I get hung up. And yes it's a blue dot. I still cannot figure how to get the voltage either. Those colors are , blue , black red , above , brown , brown , silver . old_tv_nut 05-22-2017, 07:35 PM don't just say top and bottom. Give us the colors in the order shown by the curved yellow arrow at http://www.tpub.com/neets/book2/3g.htm If you do, I suspect the value will be 11 (brown, brown) with a multiplier of 100 (red), so 1100 pf. timmy 05-22-2017, 07:42 PM Holding the cap to read what's on it , top left to right, silver ,brown , brown. Bottom right to left , blue , black , red . I have 2 of the same caps both measure different from each one . I measured the caps and one is 5.76 and the other 6.22 which my meter means 5,076 and the other 6,022 . The 2 Browns are correct but the red is or would be blue because the blue is the first color right to left. old_tv_nut 05-22-2017, 08:25 PM This shows the difference between JAN and RMA codes, but neither is making much sense to me: http://www.technicalscientific.com/PICS-5/cornell-dubilier-capacitor_codes.jpg timmy 05-22-2017, 08:55 PM Those are the colors and in that order, the silver next to the #1 shows it's a paper and infact not a mica and the 1, 2, show 1 for each and the color for the multiplier is 1 million and I don't know how to get the correct value from that, lol. WISCOJIM 05-22-2017, 09:45 PM Can anyone decifer the value of this cap the colors on top are brown, brown, silver, bottom red,black, blue. What do the schematic and parts list say? . old_tv_nut 05-22-2017, 11:16 PM Those are the colors and in that order, the silver next to the #1 shows it's a paper and infact not a mica and the 1, 2, show 1 for each and the color for the multiplier is 1 million and I don't know how to get the correct value from that, lol. If the multiplier really is one million, that would make this an 11 microfarad capacitor - hard to believe. timmy 05-23-2017, 04:19 AM What do the schematic and parts list say? . Well that's the problem, I don't have a schematic for this set there are several and the one I have is really different to the point where I cannot use it. Teletone tv 208 no ballast, and round plug and a 6x5 tube . timmy 05-23-2017, 04:41 AM If the multiplier really is one million, that would make this an 11 microfarad capacitor - hard to believe. Looking close at this cap the 2 dots that I have been saying is brown now looking closer appears that those dots seem to be the same color as the cap body, now I'm really lost. :sigh: bandersen 05-23-2017, 08:52 AM Using the diagram at the bottom of this page: http://www.tpub.com/neets/book2/3g.htm I'm thinking that it's blue, black and red or 6,000 pF which is very close to what you measured. Silver = 20% tolerance Voltage rating for brown is 200 volts, |
