I thought I read somewhere on this site that there was a way to use a Philco 20 speaker and rewire it to be used as a Philco 90 speaker for a single 47. I believe I have done that before with a Philco 20 speaker that worked well but forgot how to do it. I actually have an audio transformer for a Model H speaker I can use too.
