My newly acquired Beocord 9000 arrived this afternoon from Holland.

The deck has been serviced once by B&O 10 years ago

and have been kept unused for the last five years according to

information given by the  seller.

As I powered-up, the mechanism responsed smoothly  to all the function-buttons

and in play-mode,with  signals shown in the leds meter confirming the head picked-up signals from the tape,

I  was surprising to hear no audio sound from the headphone.

In calibration-mode, mine has the `REC-OPEN` flashes instead of `REC-CAL `.

Any suggestion given to aid me to solve and repair the faults that this deck might shine once again as it should.

The problem is caused by a faulty 7915（the measured voltage is -21V instead of -15V) and after replaced the

regulator, a dead 9000 comes to live but the output audio signals accompany with unexpected loud annoying cracking distortion sound

properly a symptom of burn fets(Tr102 and Tr202) as the outputs are taken from R156 and R256.

The burnt PF5103 fets are difficult to get, any suggestion for a substitution?
