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? W1VD amp schematic here: http://www.w1vd.com/137-500-KWTX.html (1 kW amplifier) http://www.w1vd.com/137-500-KWRev3.0.pdf W1VD LPF details here: http://www.w1vd.com/LPF.html http://www.w1vd.com/LPF.pdf -- Best regards, Chris mailto:[email protected] |
