The specific heat of selected ceramic samples of the SlK-superconductor YBa2Cu40S prepared under an oxygen pressure of S5 bar is investigated. For the most homogeneous sample, the coefficient of the "linear" term at T<<T c is ~\*-4.9±0.2 mJ/(K 2 mole), and the initial Debye temperature is 8(0)-350±1
