I’m working on an RCA Victor 65 BR 9 which uses 3 ‘high-frequency’ capacitors, as shown in the attached image. I’m not sure if I should automatically swap these out as I do with all wax caps because I don’t really know if these are available for purchase, or if there is some other type of cap that will work without increasing vibrator hash.
I’ve never hear of such a thing , but I’m not an electronics technician and there are many who know a great deal more here.
out of curiosity does it look like the regular cardboard tubes?
I guess you could do the rest and when it’s working then temporarily sub in a replacement cap to see if you can hear a difference so long as there is easy access. If not you could run leads out to test but then the lead placement could have a chance of affecting things perhaps. My gut feeling is you could disregard the warning but I’m often wrong 😉
