I know dear Humberto. And I still kept the information of your refrigerator circuit you published in one of your repair articles on my hdd backup somewhere. Of which the photos as you know were not detailed enough to make up their values to draw the exact circuit.

Good repair of this old stabilizer. When I was a child, CROWN was a brand with great prestige in my country. There were Tape Recorders, Radios, Radio Cassette Recorders, Walk Man (later), etc

In my country so voltage as frequency are not very stable. It´s a pity!

Of course, using voltage stabilizers is generally a mistake. They bother more than help in most cases. Mainly in the case reported here: only one relay to switch the outputs, which means a poor/very limited correction range. Most people use voltage stabilizers thinking that´s correct, but in many cases is the contrary. When jumping from one condition to the other, the relay contacts suppress the output voltage for some milliseconds. On applying the "corrected" voltage again after this short period, there is a possibility to occur inrush currents, depending on the characteristics of the equipment being supplied. If the equipment power supply is of an SMPS type, on applying again the voltage (when the relay completes its work), there is an NTC at the input of the SMPS that, due to be hot, presents very low resistance, favouring the creation of a high inrush current that is generally too heavy for the SMPS circuits. This switched power supply might be affected, which would not happen if the stabilizer is not used. The question: does this old lady really need to use this stabilizer? The majority of electric supply companies worldwide generally provide a relatively stable voltage, dismissing the use of any extra stabilizer.
