It's weird

I have just been reading about capacitors and found out that they run best between 20%-80% of their maximum rated voltage. I guess I should probably try and find a 6.3v cap instead? (20% of 16v = 3.2v and it's only getting 2.7v on my card!)

It seems troublesome trying to find caps in the UK! I don't know any local places, so I am having to look online, and most online places kill me with postage costs! The postage generally seems to be more expensive than the caps themselves!
