PUBLIC TV SHOWS--Public television’s 15-day “Festival 86”...

PUBLIC TV SHOWS--Public television’s 15-day “Festival 86” fund-raiser rolls to a close Sunday with a lineup of swell programs, climaxing with “Gala of Stars ‘86” at 8 p.m. on Channels 28 and 15 (7 p.m. on Channel 50).

The gala is an annual entertainment bash, and the Vienna State Opera is the site of this year’s event featuring Beverly Sills as host, James Levine conducting the Vienna Philharmonic and artists ranging from soprano Mirella Freni to dancer Fernando Bujones.

The Vienna location marks the first time the gala has taken place outside this country. The first PBS gala was staged at the Metropolitan Opera in 1980 and in the intervening years the annual event has become the traditional end of the spring pledge campaign on PBS.

Preceding the “Festival 86” finale Sunday on KCET Channel 28 are repeat airings of the “Great Performances” production of “Follies in Concert,” with an all-star cast that includes Lee Remick and Carol Burnett (at 4 p.m), and “Benny Goodman: Let’s Dance--A Musical Tribute,” a lively retrospective of the life and times of the “King of Swing” (at 6 p.m.).

The interesting-sounding programs don’t end with the close of the pledge festival.

Tuesday brings two new specials on Channel 28. “Trouble on Big Mountain” at 10 p.m. details the Navajo/Hopi relocation in Arizona (the program also airs at 9 p.m. on Channel 24). It’s followed by “American Indian Artists” at 11 p.m. on Channel 28.

Meanwhile, critical moments in the life of the scientist responsible for piloting the Voyager to Uranus will be part of the story on KCET’s magazine series, “Turning Points,” at 9 p.m. Wednesday. The program also will show skating champion Tiffany Chin as she works to regain her form after muscle damage. An 8-year-old’s first piano recital and a neo-natal care unit round out the program.

Intrigue and war top Thursday’s first-run menu. A new edition of “Mystery!” arrives at 9 p.m. on Channels 28 and 15 and 8 p.m. on Channel 50. It’s the six-part “Charters and Caldicott,” about two contemporary old-school Englishmen whose agreeable lives are interrupted by the discovery of a body. That is followed at 10 p.m. on Channel 28 by “Tenko II,” the continuation of the British prisoner-of-war series. The year is now 1943.

“Great Performances” returns Friday at 9 p.m. on Channels 28 and 15 with Placido Domingo starring in Franco Zeffirelli’s version of Pietro Mascagni’s “Cavalleria Rusticana.” And that is followed at 10:30 p.m. on Channel 28 by KCET’s production of “Gold Boxes: The Gilbert Collection,” showcasing miniatures on display at the County Museum of Art.
