In Reply to: RE: Some of the older amps had lower voltages posted by Ralph on March 13, 2014 at 14:15:41
but sometimes, on my workbench, if the wall voltage is a bit low, I see less than 130V. Don't know whether that's high or low on average.
Anyway, the point was that those Mundorf caps are not up to snuff and that at minimum 150V caps are required but at least 200V is preferred. Does that seem like OK advice? Thanks for the correction on the steady state DCV of the LV supplies.

The B+ is a bit higher. We've put 150V parts in there but they have had a 175V surge rating.
In the case of the Low Voltage 27,000uF caps. We now know they are good for around 175V. This being the maximum surge.
If I change them, as Lew recommends, with a few smaller values per phase, is there any downside to using 500V rated Lytics?.
is form factor- a 500V unit will be much larger for a given capacitance!
Thank you Ralph. I just wanted to make sure there was no 'sonic' downside.
