My first thought would be a 10A 60V Shottky barrier - but that picture looks no more than 3A tops, and you don't often find SB rectifiers in amplifiers.It is a Sony TA-F220. Build year 1991. View attachment 90681
A photo of the circuit board might show us whether it's in the power supply area and can be replaced with a 1N4007 or some other garden variety 10 cent part.
Without some sort of scale alongside the device in the photo, its only a guess at the physical size. But I'd say i looks like at least a 3A device - a 1n4148 might last a few microseconds!Diode 10E2N is listed on your pdf. Based on that I found (hopefully link works)

It looks like it is general rectifier diode and 10 EN 06 seems to mean 600 V diode. 1N4148 seems to be 100 V only so perhaps voltage rating is too low.
