content: As if the lower uf is not bad enough but having a 35v in there instead of a 50v is outright criminal (that's if I see 50v correctly on the large case) .What if someone was pushing the limits and floated 40v or 45v across them , Phiiiiiiiizzzzzzz .

content: That picture is quite old. I wonder if the picture itself is fake, as it would be quite expensive to produce a counterfeit capacitor in that manner.

content: I have seen the same photo used in a repairing old equipment blog where they are putting a new cap iside the old one so that it looks original.

content: Someone told me recently that this picture is by someone who was trying to maintain the original appearance of something.Does anyone know who took this picture?I think if you were trying to fake something this way, using Rubycon caps might be a rather expensive way of doing it.

content: Quote from: steve30 on September 28, 2014, 05:32:50 pmI believe you are correct. I seem to remember reading about someone fixing up something older and wanting to maintain the look. At any rate, if you don't screw around with your values like they did, it is a pretty cool way to keep the look, but now you also might want to check any vintage equipment you buy for someone doing that.

content: Quote from: steve30 on September 28, 2014, 05:32:50 pmAlways assuming that you buy the Rubycon's new rather than, say, recycling them from old boards. Certainly the one in the photo looks a bit tired and worn.The photo itself has been around for ages and (as pointed out)posted a number of times in the forum. Although some restorers of vintage equipment might elect to do something similar to keep the original appearance replacing a 50V 6800uF cap with a 35V 2200uF one does not seem sensible, but it might depend on the application - however I reckon anyone doing restorations will a) put a new cap inside the shell and b) go with the original value and voltage or a bit higher on the volts if space permits.I'm inclined to go with fake - not a great one as anyone with a multimeter with a capacitance range is likely to notice something is going on.
