Thanks Dennis for ALL of your informative vids, I really enjoy them. This one really helped with the capacitor & resistor ID info! The B-E-D was especially great for me! Thanks again!
Great video Dennis. I have always have had trouble reading those mica capacitors, I never know which way to read them and sometimes the colors were off. What I used to do is test them with a small capacitor checker a CIE 7705 to find out what capacity they were. I had a whole box full of them from an estate sale I bought years ago. Of course IF the capacitor was leaky the capacity usually read faltsly high. The EICO 950B would not read very small capacitors very well as you know.
Thanks Bill. One of the the problems with the micas is the colors falling off. I have several that are missing the color dots and to measure with a modern day cap tester.
thanks dennis. that was a great lesson in clearing the air for some really confusing readings. the dominios caps always got me stumped. can't tell if they are mica or paper. I have it in my saves so I can use it as a reference. thanks so much for posting!! ed
Thanks for the plethora of information regarding caps here. I now see the differences more clearly. I too, as "Bill" said, always had difficulty reading the "Domino type" capacitors. I'll be sure to check out that Philco book as well. Thank You! Tom
Dennis, This is an excellent training, or reference if you will, video for beginners and/or those developing an interest in what I refer to as ‘electronics engineering’ (in other words, learning electronics at, or from, component level and not being limited only to installing circuit boards and configuration). That was interesting when you included, “Uninsulated carbon composite resistors” and “Padders”. I haven’t heard those two for decades as it is always “Dog bone” or “Trimmers”. The only places I’ve seen (the true) trimmers are on pre mid-1950s TVs (the days before ‘flywheel sync’ in conjunction with video/sync separator circuitries) - sort of very fine line time-base/horizontal adjustment, and on calibration equipment where specific adjustment is critical. Thank you my friend. Regards, Phil.
Great video, and timely for me. I wonder if you might talk a bit about the Mica-Mold paper caps in wartime and some postwar radios that LOOKED like mica dominoes but weren't. Thanks again for the informative video!
Leaning the color codes on bumble bee caps and damino caps are the hardest two for me..I can't believe some people sell bumble bombs,on I mean bumble bee ,caps one of the worst caps out ,I either find them with a slit or blown apart.,daminos hold up better but that color takes some figuring out ,at least for me .
Thanks for sharing your knowledge, I recently found your channel and it is very helpful. It was hard for me to tell the difference between some of the tubular capacitors and tubular resistors, and the capacitor values . Also the bumble bee capacitors just looked like big resistors to me.
I need a color code I can save or print On the damino caps ,I need repair tube radios I mostly do sixties radio but I do from time to time run into damino type caps if I want to recap a radio and can't find a schematic on.it I can't replace those cap ,can you help with that anyone
At 9:26 you should have mention the arrow which needs to point RIGHT to read it correctly! At 16:40; if using in, (especially tube radios or tube test equipment), the outside foil is *VERY* important!! At 07:41, *WRONG,* that's in uF *NOT* pF
Yes pointing right. I know you always read the domino caps clock wise, but the arrows on some of the older ones are very hard to see or not at all. What do you do in that case?
Thanks Dennis, very helpful.
Thanks for watching. I'm glad you enjoyed it.

You the man Dennis, good job of explaining capacitors
Hi Dennis. Thank you for all the great videos. Take care friend.
Thanks Bobby. There is more on the way. Your friend Dennis

@@BillJAkers - I'd say "read the cap left to right; if it has a weird value or make NO since, flip it over 180°
