Here’s one from the archives. Way back, someone asked me to take a look at an amp that had suddenly stopped working. The amp/receiver in question was a NAD T752 and spent its life in this person’s garage, which they claimed had suddenly stopped working. Opening the cover revealed a rather disturbing sight. One of the 12000uF 80v Samxon filter caps had blown its top and sprayed electrolytic fluid all over the place. I have seen capacitors fail catastrophically, but have never witnessed such a large quantity of electrolyte in a liquid form. It was literally puddled up underneath the capacitors when I desoldered them. The PCBs cleaned up nicely and I was able to find some nice Cornell Dubilier which dropped right in with almost matching specs.
As your text begins with “Here’s one from the archives…” is it worth it nowadays to re-vamp a T-752?
I have one here that is faulty but I wonder if it is interesting enough to put the money and effort in.
