Replacing a 220uf 16V Cap at C302/C518, have 220 uf 25V Caps on hand, have been told in the past that the higher voltage is okay just wanted to make sure, how high can I go on a G07 Monitor Chassis would 250V or 450V matter as long as the uf Cap Value is correct?
 
The 25V caps would be fine.

I've heard that going higher with the voltage rating can be bad, but I forget the reasons why (sans the added expense).

The two caps in question I always bump those up to 25V.
 
The only problem I'd conceive of going too high in voltage is that the physical size of the cap would cause it not to fit in the spot.

Any voltage spike would burn up other parts, too, so relying on a 50v cap to pop before a 250v cap seems inane...
 
Is there a percentage of voltage tolerance from the original Cap on either the + - side, substituting lower 10V for 16V or higher 50V for 25V. basically how high or low can you go on the voltage before you get into trouble.
 
Never go lower than what the schematics/manual list. You can go as high as you want if it will fit in there...
 
Great Scott! Do you know what this means? It means that I can use that 1.21 Gigawatt Cap Kit I purchased off ebay.lol

Yep. Just don't adjust the B+ over 88vdc or you'll have to learn how to work with vacuum tubes...

I have no experience to contradict the above; but just a potential theoretical concern...

I understand that, in general, the the normal ESR of capacitors is higher for higher voltage rating: http://electronicrepairguide.com/blueesrmetertestchart.jpg
It seems concievable that the higher ESR may have an unintended effect on the circuit.

So personally, I have no issue subbing in a voltage rating one or two steps above the original. But I don't go overboard, putting in 160V or 250V caps to replace 10V or 16V parts.

I've done that when I had to, with no adverse effects. Now, I wouldn't put a 2200v cap in place of a 16v cap...
