[Drake] Drake L-75 Amplifier Question

[Alfred Carlson]

I have recently restored a beautiful condition L-75 with new tube and
electrolytics.  I noticed that the relative power coupling capacitor had
been removed.  At component location C-40, it's a 6.8pf cap,  I need to
know the voltage rating.  Three to four DCKV I think should do it but,
does anyone know what the factory voltage rating on that cap should
be???   Thanks and 73 de Fred...
