Rifa, a Swedish capacitors manufacturer, produced many of these metalized paper capacitors. The epoxy housing srinks over time and compressing the metalized paper roll inside and ended up in short circuit. These capacitors are intended for supressing arcs ect. in mains parts. These are used by many brands in the world and I found them in nearly any European brands but even in Japanese brands like Akai, Luxman ect. I had a bunch of these capacitors new on stock but after 10 to 20 years the epoxy housing start to crack recognizable of al the hairline cracks. In my workshop is it standard practice to open up a device and check for visable damage, burned parts and see if Rifa capacitors in it before the device will be plugged in. If you find Rifa capacitors with hairline cracks in it remove or replace them first. For reducing arcing they can be temporarily removed, if for motor control like in Revox open reel machines for example replacement must be done before switching on.

It's an unavoidable failure mode for any (molded) paper capacitor. The epoxy housing just accellerates it but the ones in the white housing blow up as well.

As a teenager I once found and salvaged a Luxor (Swedish brand too) TV set from trash. Brought it in and plugged in. As first impression, it seemed to power up just fine, but almost right away I saw exactly same kind of smoke coming out. Pulled the plug and opened the thing up. Rifa capacitor on mains cracked and burned. Replaced it and the tv set served for long, long time.

Not just audio gear. I am still miffed than after this happened on her expensive Viking sewing machine my mother thought the motor had burnt out so threw away all the accessories like the pedal and asked me to take the machine to the tip. When I looked inside it was the RIFA capacitor across the motor that had blown. I could have easily fixed it for her without even using a soldering iron but too late.

That RIFA was not an electrolytic. It's an X2 class; they're usually connected across the mains for RF suppression purposes. Indiscriminate replacement of electrolytics is often unnecessary. Some types/brands in certain situations will definitely need replacement while others will last for many decades.

At least it wasn't in your vacuum cleaner. That spreads the smoke throughout the room super quick. Check out the TRS80 PSU RIFA capacitor video to see what actually happens. The person who filmed that was so confident the capacitor would film he pointed a camera at it. As it was he had to wait over 20 minutes before all the magic smoke escaped.

I didn't use it in a while, because everything now is computerized and digitalized so no actual need, but when lastly used it worked ok.. Cheers!

Turntable worked but on a certain moment the arm started returning after a few minutes. The sound of the turntable was very pleasant (with Shure 97HE instead of the Ortofon) Opened the Revox and 1 of the 3 Ptc was cut, think 50% was left of it, broken off and that must have consequenses, this might be the problem? The other two looked good but might be faulty too..
