There is an ongoing debate in the vintage radio press as to whether one should just replace the faulty capacitors, or the whole lot. Everyone seems to have a different opinion on this. I tend to take a middle line on this subject.
I used the coupon to stock up on a couple of capacitor assortment boxes realizing I could use the capacitors to recap the Glendon at some point. Sure enough, upon opening the set up I discovered that one of the wax capacitors, No. C11, on the power line had exploded.

How to choose capacitors and install them in tube radios is explained in non-technical language. We hope you find this capacitor advice useful re your vintage radio repairs and restorations. Capacitor Tips for the beginner :. A typical old paper capacitor top can be replaced with either a new "axial" film capacitor middle or a new "radial" film capacitor bottom.
However, I think the period when these scopes were built was one where plastic film caps were being used in place of paper caps. I am not sure how you tell for certain from the packaging other than waxed cardboard cases are definitely paper. Plastic film caps will still be good and will continue to be for years to come.
