The first one has the Siemens logo but I'm not sure about it. I'm guessing that it is like this 2SK952 800-volt MOSFET by Fuji. It would be plausible as a power supply part for a tube amp:

The second one is probably a TL431A programmable voltage reference:

The third one is probably an 8-volt regulator:

Google is your friend when identifying part numbers.
