LeCroy 9354AM oscilloscope power supply

Lecroy 9354a PSU Problem

Hi there, I have the same scope (9354A) with exactly the same problem. It would appear that the main switching transistor a MJW16010 has gone with a big bang! lifting the base track as well. This makes me believe that this card may be unrepairable? as significant damage may have occured elsewhere.
I am interested as to what response you received from Lecroy and, of course, what you did in the end in order to use ths scope?

Many thanks Rob (Bluerobboman)
