So, the next hurdle that needs to be dealt with is a file conversion software that can convert the now JPEG image to a VP3, the file format needed for her machine.

Surprisingly the main board showed no signs of scorching or burns, being an amp of 25 years old, and being pre-2005, the year the bias drift issue was resolved. The board was clean. Keith went on to assure me that not all the PCB boards were faulty, that some boards never had a bias drift issue. Marshall UK reaffirmed this via email to me when I was seeking info on the faulty boards, and what lots in the production line were good and bad, they too assured me not all boards were bad, and it was possible I had a good one.
