Valve Amp Schematics

Capacitors, query, sizes etc.?

I am building a valve amp, and the schematic, reads that a 63v cap is used ( for example ), will it still be fine if I used a 350v cap instead? Seeing that I didn’t find a 63v in that model.

I think that it should be fine, since the cap can now handle more volts?

Can someone please help me?

Thank you..

You should get a capacitor closer to the correct voltage. While the voltages are maximum working voltage, with some electrolytic capacitors the voltage is important in the cap’s value. The higher voltage creates a thinner chemical layer between the plates increasing the capacitance. A lower voltage reduces the capacitance because it doesn’t create as thin a layer. I’d use a cap that was no more than twice the original voltage rating for proper operation.
