repair for Mark Levinson 383

Hello, My ML383 amp recently failed. I sent it to one of the service centers and was told that it'll cost over $1300 to get it repaired. The reason they said is that a capacitor on the left channel voltage gain board failed in such a way that the circuit board itself has been damaged and therefore cannot be repaired, and as a result this board needs to be replaced (about $950 plus labor).

I'm devastated. I wonder if anyone has had experiences with repair for ML components. Any advice would be greatly appreciated.
There is two 44000uF/75V filter caps on each channel.
Are you saying one of the caps failed?
I am not buying the circuit board cannot be repaired. A good technician can trouble shoot which resistors are burnt and replace other damaged parts. Also replace all power supply filter and regulator caps.
