What about a switch on the first capacitor?

of a CLCLC ps as an alternative to switching the B+ line?
In my amp which is a PP Class A amp the power supply is LCLC and is on a separate chassis. I would also like to use this ps for other amps such as single ended amps and would like to make the voltage range wider. Currently the Av is 350 with tube rectifiers. I was trying to get it to 400vdc to see what sonic difference that would make. THe amp has a LCLC filter supply and I could install another C in the C1 position. I have a 5uf x 600vdc cap for C1 and that should bring the B+ up past 400vdc. Would putting an appropriate switch on either the + or - leg of that cap be an issue? The switching would only occur when the amp was off. cheers, Dak
