Abstract
The Arecibo 1612 MHz survey of a complete sample of color-selected IRA S sources with 25 mu m fluxes S(25) > 2 Jy detected 393 OH/IR stars. A complementary 1667 and 1665 MHz OH survey of these objects is present ed here. Main-line masers have been detected in 238 surveyed objects: 18 exhibit only 1665 MHz emission, 220 exhibit 1667 MHz masers, and 11 9 exhibit both. The main lines were not detected in 159 objects.
