Sansui G6700 Resistor question

[josumo1]

A Sansui G6700 I picked up will power on but no relay click, no sound. While inspecting inside noticed board F-3060 Resistors R605 is 390 ohm 5 watt, R606 is 330 ohm 5 watt and R607 is 390 ohm 5 watt. The service manual lists R605 @ 470 5 watt R606 @220 5 watt and R607 @ 390 5watt. There is also a scorched area around R605/ R606. The resistors look original, could this be a factory mistake or a service manual typo? Thanks

Service manual error - the manuals and schematics were printed early on, and production changes never made it to the manuals because of that.

Remember when changing components, always change like for like, just use the SM and schematic as a guide only. Remember the unit passed all the factory checks and worked for years like this...

(But you should look for signs that someone has been 'in there' before, as this could indicate that correct factory installed components have been messed with, take pictures and post here if you are not sure).

Thanks for clearing that up! I will order new resistors based on what is in the unit now!
