No senators were willing to be the first to step forward to offer amendments to the tax-revision bill today. The Senate continued with slow-paced discussion without votes. ''My hunch,'' said Senator Bob Packwood, the bill's floor manager, ''is that no one wants to go first if their amendment is to be beaten, 55 to 45 or 60 to 40.'' Tonight Senator William V. Roth Jr., a Delaware Republican, proposed a ''sense of the Senate'' amendment. It states that Senate conferees, when they meet with House conferees to resolve differences in the two chambers' tax bills, should agree to fuller deductions for Individual Retirement Accounts than would be allowed by the Senate bill. Conferees are not bound by such an amendment.

Only when all seemed right to Dorothy Pietrucha - when the crystal gleamed, when the champagne was chilled, when the flags and place settings and fresh-cut flowers were in place -only then, after 13 hours of preparation, did she relax and start enjoying her Saturday. As she waited for her guests to arrive, she looked forward to the time when one of them would be the host and she the guest at an equally elaborate dinner. For the past four years, Dorothy and Frank Pietrucha, along with three other couples from West Orange, N.J., have been holding rotating gourmet dinners: Each couple takes turns at preparing a superb and elegantly appointed meal, knowing that for their efforts they would be treated to three stellar nights out later on. ''They knock themselves out for us just as much as we knock ourselves out for them,'' said Mr. Pietrucha, a freelance graphic designer. Mrs. Pietrucha is manager of the Morristown branch of the First Fidelity Bank.

IN the five years since the state enacted its ''bank haven law'' - the Financial Center Development Act, which granted businesses favorable income-tax treatment and ended interest-rate ceilings - 26 banking companies and more than 3.5 million square feet of new offices have arrived in New Castle County. So much speculative building has taken place that some brokers fear as much as a five-year surplus by 1990 if all the proposed office projects - totalling a further 3 million more square feet - are built. Beginning in 1981, the banks began moving into unused strip shopping centers, obsolete government and utilities buildings and any other available office structures. By the following year, developers were offering build-to-suit construction or putting up speculative projects. Some state legislators, concerned about highways being choked with traffic and a deterioration in the quality of life, are proposing laws to limit development or key it to the impact on highways.

Still stung by its record fall on Monday, the stock market declined sharply early in yesterday's session before recovering to finish the day with a loss of less than three points. ''After yesterday, more people are saying, 'I don't want to play this game until it settles down,' '' said Charles Comer, a market analyst with Oppenheimer & Company. On Monday, the Dow Jones industrial average fell a record 45.75 points, or 2.43 percent of its value. Selling pressure carried over into yesterday's session, sending the Dow down 16 points more at its worst level.

An article in the SportsMonday special report this week about the United States Open, on how to enjoy the tournament, misstated the hours for the Inn at Quogue. It is open every night during the week of the Open and every night for the rest of the summer.
