Please . . . advice on filter caps

[AndrewT]

your 40+40Vac transformer should give <+-63Vdc as a PSU with very light load on it. My 230:40+40Vac transformer gives +-58.5Vdc when mains is at 240Vac and total quiescent current is set to ~200mA.............

The UK tolerance range for mains voltage is 216Vac to 254Vac.

If you look at IEEE statistical data on mains voltage variations the nominal +/-10% is routinely exceeded; +15, -30% is fairly common and there's data out to +25%. That means if the mains run high 63V caps may blow depending on the excess voltage duration and how close the caps' actual breakdown is to rated voltage.

The OP and, presumably, most folks reading this thread are not in the UK.

I made a statement of what I find with stated equipment and I confirmed two posts later the tolerance range of the mains supply I have. This information was supplied to try to help the Member solve his problem.

Your reply was addressing a different subject.

Whether Members are in the UK or elsewhere does not change my experiences nor does it change the message in your post.

I object to and resent your put down that I am not considering the majority.

I'm sorry you're taking it personally, but I would feel negligent if I didn't raise the limitations of using 63V caps on a 40V trafo. There's enough context in the thread now that a reader has sufficient information to investigate whether or not they wish to risk some cheap (but good) caps:

For this first build I suggest you buy some cheap (but good) 63V caps

If we need to discuss this further let's avoid clogging up the thread by taking it over to private messaging. Thanks for your understanding.
