Whenever the topic of "recapping" comes up it typically follows that some may say "recaps are unneeded". In general I have no problem with that as, at some point, it is up to the owner to make that call.
To that end, I have always wondered..... "how bad do they get"???
At this point I have replaced 35 caps in my SBE Console V (ONE of them I have excluded from this test, as I pulled one of it's legs out when removing it. GOT to DESOLDER the RIGHT HOLE!!!!)
What I have done here, just for giggles, is to run each cap that I have already replaced (not quite finished, a handful more to go!) across my ESR tester. Just one of the little cheap-o Chinese ones.... no lab insstrument!
I did this to get an idea how bad things were across the radio as a whole.
The more experienced here will most likely already know statistics like this.... the less experienced here might enjoy seeing what I found and get more a "feel" of their own as to whether they should or should not commit to a recap. As always, your mileage may vary!
Please watch the units on the capacitance measured. Some were so bad that I believe the tester thought they were not electrolytics and so did not show an ESR value. A small few.....failed to even read as a working device. It is what it is!
(PS I hope the formatting turns out right!)
