Again: Zener Diode ID

[Reinhard Zwirner]

Hi,

I have to replace a zener diode (D7) in a Kenwood KA-1500 PA.
With the help of a magnifying glass I found the number:

1875R ("75R" is about half the size of "18")

Does anyone of you know the zener voltage of this diode?

TIA

Reinhard

Thanks for the hint. In the meantime someone has sent me the
schematic: the Zener voltage is 18 volts (surprise, surprise).

Best regards
