Hi All,
I have a 30+ year old Marantz PM310 that is blowing fuses. It appears that one of the output transistors (Q732) is shorted (Q731 is fine). It's a 2SB633 which does not seem available from the usual suppliers. Is there a more modern equivalent which would do the job?
The complimentary NPN (Q729 & Q730) is a 2SD613.
I have attached the service manual.
Many thanks.
