Hi.. i replace the 2sa684(q444) with a92 now problem soleved ther is no leakage current. I think 2sa684 for not suitable for this apllication as the maximum volatage on Vceo is 50 but in this circuit its 54volt i think thats why this leakage current but for a92 Vceo is 300 volt.any way thanks alot for your support i apriciate it..may be tomorrow i will get correct tramsistors ie. A992..then i wil replace it
