LF: LPF for a valve based (tube based) LF amp?

[Chris Wilson <dead.fets@gmail.com>]

Hello LF'ers,


My next contemplated project is a GS35B valve based LF amp. I have the
HT supply, a couple of GS35B's to play with and a suitable filament
supply. My question is can I build an air wound LPF based on exactly
the same values as the one I use on my W1VD FET based Class D amp?
That gets pretty warm and I use a small PC processor fan on the centre
toroid, but I am unsure if the filter characteristics are specific to
a FET based amp in some ways?
