[sdiy] Zener diode wattage tolerances

[Bob K]

Hi folks.

I picked up a homebrew synth at a yard sale over the weekend.

Documentation and some crude schematics came with it and, after
opening it up, I saw this burnt out component:

The documentation tells that it's a zener diode (8.2V, 2W, 10%).

Looking online, I'm finding 8.2V zener diodes but only with a 1.3W and
lower or higher than 3W.  Nothing in the 2W range.

I'm guessing a 1.3W diode should the job, right?

This is my first time trying to diagnose and repair something.

Thanks!
