I have acquired a Philcophone which, apart from being in a terrible state, is missing its nameplate. I can find info about a model 901 with tubes 2 X 6K5g, 25A6G & 25Z6G but my set has 2 X 75, 18E & 25Z5 & a 301 ballast tube. Can anyone shed any light on the model of this set & does anyone have a circuit diagram?
