beetlemania Posted January 26, 2020 Share Posted January 26, 2020 I didn’t read every post in this thread so maybe I’m repeating information . . . PPT is a polystyrene film cap. It is a very high quality type and should last a very long time. Why does “hand made” make a difference? Electrolytics are caps that will drift with time, say 15-20 years. I would be inclined to leave PPT type in unless you want to play with other caps (caps do sound different). If you have any electrolytics (looks like two electrolytics on that board) of that age I would definitely replace those, and with a good film cap if available in the correct capacitance.
