This is not a competition I am eager to win! With Rifa capacitors, everybody eventually loses.
I have gone through most of my pieces, but there are a few more HP pieces that I know have Rifas and a few more that I suspect also do. Why is it that those pieces are on the bottom of my stacks with 10 heavy pieces above them. My back already hurts from moving a ton of equipment around.
Photo shows the carnage so far... 57 Rifa caps preemptively replaced. Many of them look far worse in the picture than I originally found them. This is because I often found it easier to remove the cap from the component side (when getting to the foil side looked like a pain in the butt) and so were chipped or cracked or mauled by rocking them with pliers until they pulled free.
Most of the casualties were from HP and Tektronix pieces in the 1980s and early 1990s. The worst offender was the HP 8160A pulse generator with nine Rifas, followed by the HP 6621A power supply with seven Rifas and the HP 8080A word generator with six Rifas.
Whereas most of the Rifas are lurking right near the AC jack on the back panel, there were a few cases where HP used them in "non-standard" places, like after the diode bridge in the switching power supply of the HP 3764A digital transmission analyzer or on the output of the HP 6621A power supply.
I didn't do anything with the sealed line filter modules found in many pieces. I know Schaffner has a bad reputation, but replacing Rifas at about 35 cents a pop (no pun intended) is a lot nicer than $30/each for a line filter.
I will probably end up with a count of about 70 Rifa caps replaced. Maybe I will glue them all to a piece of cardboard, frame it, and hang it on the wall.
