Capacitors????
brainstorm:
I have noticed that we didn't get the problems with capacitors when the snickers bar was called 'Marathon'
They changed the name to Snickers and all of sudden we are flooded with Samsung TV's with bulging capacitors!
Coincedence? I think not!!

Brian, you might have a point there.
my point about the correct values, I should say the correct capacitance, although you can use a higher rated capacitor in most cases (and the set will work and sets will work with low capacitors before they give up) I have found that if you use caps that are a lot higher in value (if we’re talking about electrolytics) then its more of a practical consideration, they’re more expensive and often to large although as I’ve said you can in most cases get away with it.
With the case of a 820uf being a slightly odd value engineers will often sub a 1000uf taking time to wedge it under the heatsink or stuffing them out of the top. If a customer sees it then you can expect a good ear bashing, its not great practise, so I'd say yes, "try" to stick to the correct value.

Did you.get the email I sent?

Hi Andy
I emailed your email address on this site, so it looks like you didnt get my email and I'm not getting yours!!
Regarding the capacitor debate, I always fit the exact capactance value, but regarding the voltage I try to make sure the working voltage is not dramatically higher than the original or this can effect the ESR
ie fit a 16v in place of a 10v but don't go sticking a 250v one in!!
And I didnt realise anyone was still using 85 degree caps!!

Brian,
Look in a vestel psu next time you have one. Sites will often sell lots of caps in a "bulk buy" at a cheap price and you'll find they're often 85degs
Yes, a degree of common sence is needed with caps. you can upset how a cct. works by changing the cap values although size probably prevents you from doing this.
Ye, I got your email and replied to it, you should have 4 emails from me (try looking in your trash).
I'll resend from a different email account
regards
Andy
