telefunken opus 6 rectifier
#6

I'm not surprised they are known for failure. Without the fins to cool them they are just asking to overheat and fail. I would think that a modern diode bridge which can mount to a proper heat sink would be a much improved replacement for that disaster waiting to happen. One of the small, square ones with the hole through the middle for chassis or hear sink mounting would do the trick.
