63V smoothing capacitors for

88.19.142.194

megalomaniac

I am thinking of replacing the old, cheap 80V / 10000uF smoothing capacitors of my power amp with Panasonic caps from the TS-HA series (I have read excellent reports from the users of these 'snap-in'-type caps).

However, the maximum capacitance value offered by PANASONIC in the 80 V range is 6800uF.

http://industrial.panasonic.com/www-data/pdf/ABA0000/ABA0000CE31.pdf

Given the fact that the secondaries of the power transformer of my power amp measure *45* V, could I get into trouble if I replace the actual *80* V /10000 uF smoothing caps with *63* V / 10000uF caps?

Thanks in advance for any input.

45vac X 1.414=63.63v PEAK.
Your caps MUST exceed that rating by +~20%=76v, so 80v is the next std rating UP. (20% is a rule of thumb safety-thing)

I'm sure there are other caps available besides the Panasonic.

PEAK voltage from 45vac is approaching 60 volts. THAT's what'll kill the caps.
Go with higher voltage, like the original designer called for.

63V will have plenty of headroom, go ahead and use them. In
fact 50V caps would work of you had to use them.
