Check all the simple stuff first like making sure all the cable connections to/from the alternator are clean and free of corrosion. This also means cleaning all the connections at/on the starter solenoid, battery terminals, and the ground cable connection points. Then check that the belt is properly tensioned.
On to terminology. The terms "stabilizer" and "regulator" have different meanings and are often used incorrectly for each other.
The voltage stabilizer is associated with the gauges on Triumph cars from the early 1960s onward. The stabilizer's job is to reduce the car's operating voltage to an average 10V to power the bimetallic temperature and fuel gauges. The stabilizer is an electromechanical switch whose output voltage will only influence what the gauges read/do.
The other part more likely to influence your car's behavior is the voltage regulator. On cars with generators the regulator is a remotely mounted black box about the size of two small clenched fists. It typically was mounted on the firewall... on that housing where the fresh air intake for the passenger compartment is. On cars with alternators, the regulator is no longer a separate device, it is integrated into the alternator itself along with the diode bridge. Your best option is to remove the alternator and take it to the local auto parts store. Ask them to bench test the alternator. This is typically done for free as they hope you will buy a replacement alternator from them.
If they tell you the alternator is bad, believe them and consider buying a rebuilt unit with lifetime warranty as the replacement. If they say the alternator is "good", have them load test the battery after you reinstall the alternator. If both the battery and alternator check out as "good" yet the flickering continues, you may have an intermittent failure or you could have a high-mileage alternator where the brushes are approaching their wear limit.

: Sorry I don't know where exactly it is
: under the dash, but it likely has
: nothing to do with the problem since
: none of the circuits involved run off

: It serves the instruments; the lights,

: The only thing that the circuits may
: share is the ground...
: Good luck!
