Hi again,
Just a quick post I was going to show what is inside of those fiter caps. Your filters may be indise of a metal can, but the idea is the same.
This cap was actually "working' in the set. On borrowed timem failure was going to be "who knows when".
The caps are rolled with a paste substance that dries out even though the cap was sealed with resin.
You can see the dried out electrolyte, and then upon unrolling the cap, you can see how the foil deteriorated. That damage was not caused by unrolling. It was like eaten away. Needless to say, this cap was going to fail and soon.
I know there are some that believe in the 'if it ain't broke, dont fix it' adage. That may work for some things, but not caps IMHO.
After seeing this, I say, why take the chance? Why risk damage to a cherished set, just to save a dollar or two on a modern replacement?
For those like me who want the underside to look original on some sets, you can simply 'restuff' the old capacitor tube with new parts, then seal it up. I think that's what I did on this one. That way all the labelled Philco logo caps are retained.
I hope this shows a good reason why we should recap.
Take care, Gary/
