The Strobotac Type 631-BLS8 is the equivalent to the Type 631-BL, with the exception of the Power Supply requirements of the Type 631-BLS8 being 230 Volts at 50 Hz, as opposed to 105 - 125 Volts at 60 Hz. The 631-BLS8 was first listed alongside the Type 631-BL and Type 631-BLS3 in the General Radio Catalog O (1956), which was reprinted in September 1957. The Type 631-BLS8 would not be relisted in Catalog Q (1961), which introduced the new Strobotac Type 1531-A.
