Here is how to replace masked roms and jumpers
Quoted from Zablon:I am working on these boards for timab2000. I was doing some research and found quite a few pictures with resistors in place on CR1-3.
If you wipe off the dust, you will see those are actually glass diodes.
Like Marco says, make sure the replacement diodes are mounted well above the circuit board for proper airflow.
