In June 1974, Drake—Chenault sold the station to San Diego-based Brown Broadcasting, owners of KGB-AM-FM; the station re-branded as "Super Stereo K-108", featuring top 40 music, and album-oriented rock at night. By early 1975, the station had shifted to an album-oriented soft rock format branded as "The Mellow Home"; the format was successful throughout the remaining half of the 1970s. During the 1980s, the station pivoted to a soft adult contemporary format, remaining successful throughout the remainder of the decade. Despite changes in ownership and format, staff turnover was rare. On-air personalities included Dusty Morgan, Dave Allen, and Tom Nakashima. KXOA-AM-FM simulcast broadcasts of "American Top 40" with Casey Kasem during this period. K-108 FM also had a strong commitment to news and public affairs programming during the 1980s through the early 1990s. News director and morning news anchor Ken Hunt and his news team, (primarily Nanci McGraw from 1981 to 1986), won multiple journalism awards from the Associated Press TV Radio News Association and the Radio TV News Directors Association for news programming distinguished by its local coverage, creative use of natural sound and conversational style.
