Hantarex Polo Repair Log

Problem: Weird "wavy" horizontal linearity. Crosshatch pattern would gradually get narrower, and then wider, and then repeat. Vertical linearity was fine.

Simulation of H-Linearity problem of Polo

Solution: Discovered that D135 (BYV95C) was burnt and broken in half. Replaced with a BYV28-200, since that's all that I had and it is rated higher than the original part.
