A replacement for that FET is a ECG brand ECG221 or a NTE brand NTE 221
Also tell the repair tech that if it's the preamp with select tone that's not working, it's output goes into the first half of the IC chip on the other preamp board.
This all means that if that IC chip is bad that the selecttone channel will not work also.
