I have a stupid question but my excuse is that my stroke that I had a few years ago makes me sometimes hesitant because I have simply forgotten.
I am building a tube preamp and I use SMPS for the glow but now the secondary glow is not used on the main transformer my question is because it has two 3.5V with center tap that is connected if I want AC glow, my question is then should I connect the center tap to the chassis ground or not now that I use SMPS.
