Marantz 4300 P700 small signal transistors

[ocdecio]

Just leaving this info here for reference. I have a very original 4300 on the bench and as I am going through the left P700 power amp I am seeing a couple of discrepancies with the SM that may be helpful in subbing some small signal transistors.

H717 to H720 - SM 2SC945 Board: 2SC735 - sub KSC945C?
H721-H722 - SM 2SA733 Board: 2SA562 - sub KSA733?

Thanks for the info. Might want to consider ask an admin to move this to Marantz Service Manual Error sticky thread.

Not sure if this is really an error - I think they may consider these interchangeable?
