[attachment=19394]The radio I have, I believe, is the last model with the 36 tube before it was changed to a 77 tube. My radio has a broken mica cap between the plate of the 75 tube and ground that is not shown on the circuit diagram here https://philcoradio.com/library/index.ph...-model-89/ The broken cap is a micamold with a color code of brown, yellow, brown. In the later versions of the 89 with the 77 tube there is a 250 pf cap here. I have attached a pic of the cap. Is a 250 pf cap ok for my radio? Thanks, Bob
