I've been working on an old Phillips tube amp, and the rectifier is solid-state, but germanium. How do I determine what to replace it with? Will I just need to resort to soldering some diodes together, of some value or other? It's above my "pay grade" for sure...

It is probably a selenium rectifier. Has metal fins?

Replace it with a silicon bridge.

The selenium emits poison when they fail...

Selenium rectifiers had a shorter lifespan than desired. During catastrophic failure they produced significant quantities of malodorous and highly toxic fumes that let the repair technician know what the problem was. By far the most common failure mode was a progressive increase in forward resistance, increasing forward voltage drop and reducing the rectifier's efficiency. During the 1960s they began to be superseded by silicon rectifiers, which exhibited lower forward voltage drop, lower cost, and higher reliability.[6] They are still manufactured for exact replacement purposes, but are not designed into new equipment.
 
The unit is metal, with no fins that I can see and square, about 3/4 of an inch on the side. It is labeled as so:

B250C75
e-F1080
Made in Germany

Will any silicon bridge work, or do I need to tailor it to the amp?
