Sansui 1000 Wiring Symbols ^ < > # * = ?

[adreniline]

Probably a basic question for you techies out there, but not knowing enough about electronics, especially from Japan. In the following pictures I have taken, there are symbols on my wiring diagram and on the I guess what you might consider the ledger. The wiring diagram shows a symbol in front of the 30u/10v cap, 170k resistor, 15k resistor etc. In the ledger the same symbol appears, followed by Japanese writing. There are 7 symbols followed by Japanese writing I'm sure if I could read Japaneses my answers would be solved. Anybody have any clue what these seven symbols represent, even a few might be helpful

It probably has something to do with the design or tolerance of the component. Use good quality parts and don't worry too much about it.

well done

Thanks for the help, good to run into such knowledgable people. I have received a receiver that has been worked on by other, bad workmanship and a few other issues to remove before I can call it properly restored.
