Roland Studio Bass 100

[Carlosraj]

Dear Friends,

I am trying to fix a Roland Studio Bass 100 amp that belongs to a friend of mine.
There is no problem with the preamp. I checked the power transistors and both have short circuited. The problem is, both the power transistors (TO3) numbers have been erased. I would be very thankful if someone could provide me a schematic or let me know what are the two transistors numbers are.

Thank you

Carlosraj
