Dried out electrolytic capacitors are one of the most common failures in far more modern equipment too. While I try to restore old gear as close to original as possible, I restore it to use it and electrolytic capacitors get replaced. I've occasionally placed new capacitors inside the gutted housings of the old parts but that's a lot of work so the technique is reserved to particular pieces. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
