The advent of selenium rectifiers in the 1940s was a very welcome new option to circuit designers, consumers, and servicemen. Before that, vacuum tubes did the job (with some use of copper oxide rectifiers). Selenium rectifiers have the advantage of ruggedness and reliability over tubes (~85% vs. 60%, respectively).Web

That is what most rectifier manufacturers recommended. The resistance would depend on the voltage and current rating of the rectifier. For example, if the rectifier in the TO is rated for 75 mA and is powered with 120 volts, you'd expect the lowest load resistance it could carry to be 120 / 0.075 = 1,600 ohms.Web

A selenium rectifier for line-voltage service drops about 7 volts. A silicon rectifier replacing it would drop about 1.2 volts, a difference of less than 6 volts. The purpose of the resistor between the rectifier and the first filter cap is to limit surge current at turn-on to about 1 amp. Its value is usually 50 to 100 ohms.Web
