    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.

    Any advice is greatly appreciated.

    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 😉
