capacitor values

I am very new to vintage radio restoration. When replacing caps in my Radiola 61-3 it calls for caps in the 700 and 800 volt range. Where can I get caps this high in voltage?

A good resource for HV caps is at www.justradios.com.

These guys have a TREMENDOUS selection of capacitors along with information on how to apply them to antique restoration.

Also see www.justradios.com/capacitors.html.

:Lou,
Thanks for the great information. I am sure that I will use it for many years to come.

You can use the common replacement capacitors that are rated at 630 volts. There is no voltage in the radio that even comes close to 630 volts.

:Thanks Warren,
I just recieved some caps in the mail. Happy to know that I do not have to order more.
Thanks again. It is nice to know that there are so many good people in the radio restoration hobby.

Sometimes, transient voltages can be higher than what you measure with a DC voltmeter. You can always put two identical caps in series: the voltage rating is doubled and the capacitance is halved.

I have seen 1600 wvdc caps in audio tone control circuits. Not that a dc voltage would ever approach that in this application.
A cap really only does any work when an ac voltage is put across it.
Audio circuits and speaker crossover networks seem to greatly over-rate their components for high sound quality.
