Can someone indicate another place to buy these kind of hardware online.
The pcb from a 2501A will be compatible with the peices from a 2501B, but you must be sure the replacement pcb can be downgraded to at least 3.55.
If you do not ensure this, then you will be unable to make your blueray drive compatible with the new PCB.
