Default Technics SU-Z25

Does anyone have a schematic for Technics SU-Z25 amplifier or does anyone know what the value of R451 should be.

Thanks

I have that service manual, but there is no such resistor R451. Instead of resistor R451 there is a jumper, labeled with J. In my amplifier resistor R451 is connected in series with D407 and R405 66Ohm/2W, but in this manual R405 is 82Ohm/2W, so I will put 22-47Ohm.
