Voltage regulator location? Need a new alternator?

Hey guys, I have been having electrical issues with pulsing dash lights and the radio cutting in and out when I bring up the rpms. It's also been blowing fuses for my tach and voltage gauges. My thoughts are that it's the voltage regulator. When testing the voltage when the car is running it is putting out around 15.7 V. It's a fairly new alternator(around 6 months old), so I removed it, but when looking at it, I can't tell exactly where the regulator would be. I'm hoping someone more familiar will be able to point it out for me. I'll attach photos, let me know your thoughts and thank you in advance!
