This part appears to be equivalent to the Fender part 16282 from all information we were able to locate.

This optocoupler can be safely installed with the silver dot face up or face down. The dot represents the non-polarized side, so pay close attention when installing this part. Installing with the silver dot in the wrong direction can result in damage to your amp.

Hey Martin. The side with the dot is a neon bulb so it won't read with a multimeter. The other side is the photosensitive resistor which measures very high resistance with no light present. Once the bulb is lit, the resistance will drop.
