You said "transistors" a couple of times, so on the off chance that you mean the transistors burned up and you can't read the numbers on them to see what transistors to get as replacements, you can get the Service Manual from ElektroTanya:

Were you trying to send your Keyboard into orbit?
You may well have damaged far more than the transistors on the circuit board.
If you can repair the keyboard yourself then that would be great but if you have to take it to a repair shop then the cost of the repair is likely to be far in excess of its worth.
As the 443 is now an old keyboard maybe it is time to look to buying a new one.
