Hi all,
The above mentioned subject amp came with blown caps. On inspection found bad transistors in driver board after changing the caps and transistors amp came on and got good oscillations on the outputs. Few days after the amp came back with same blown caps. Any ideas?

If you shine a bright light from the back of the board, do you see any dark areas between the pads for those transistors and and any other pads?
Is R94 within tolerance?
