Stern SDU-100 sol driver bd query

[paddythegreek]

I was testing this board using a transformer an rectifier bd when I caught the pos lead of my dmm across the high volt test point and a leg of a resistor.
After the flames had one out I’ve got a few buggered bits. Can anyone tell me the value or resistors R53 and R74. Found the value of R55 (1.2K) Thanks Ken
