Trying to find a substitute zener mz-150 for a Pioneer sa 708 ? It is missing and is located between the two mid size caps on the rear section . Why this pioneer has no part location numbers printed on the board ?

A missing Zener?

How odd.

It's a 15v Zener. NTE5024A and 1N5245B are substitutes.

I presume it's D510 on the lower right of the SA-708 power supply schematic here?
